15 Neuroscience Research Topics for High School Students

Neuroscience explores how the brain and nervous system influence behavior, memory, learning, emotions, and decision-making. As an interdisciplinary field that draws from biology, psychology, medicine, and cognitive science, it offers many opportunities for students to investigate complex questions about how the mind works. Conducting a research project can help you explore a specific area of neuroscience while developing analytical and scientific inquiry skills.

Why should I do neuroscience research in high school?

Neuroscience research allows you to examine topics that are rarely covered in depth in a typical high school curriculum. Depending on your project, you design experiments, analyze behavioral data, investigate cognitive processes, study sleep and memory, or explore the connections between brain function and human behavior. These experiences develop research skills, deepen your understanding of the field, and help you identify areas of neuroscience that interest you most.

In this blog, we’ve developed 15 neuroscience research topics for high school students to consider.

If you’re looking for online summer research programs, check out our blog here.

Key takeaways

• These topics span behavioral experiments (risk and reward decision-making, fear conditioning simulation), technology and lifestyle research (blue light exposure, digital notifications, handwriting versus typing), and physiological measurement studies (mindfulness and stress markers, sleep and emotional regulation).

• Several topics connect neuroscience to specific brain regions and mechanisms, including the amygdala (fear conditioning, mindfulness and stress), prefrontal cortex (adolescent decision-making, bilingualism and cognitive flexibility), and hippocampus (handwriting versus typing and memory retention).

• Many projects are designed around accessible, low-cost methodology, including smartphone tracking, mood rating forms, and simple timed tasks, making them feasible without specialized lab equipment.

• A few topics, like the placebo effect study and sleep and emotional regulation research, include built-in cautions about interpreting results carefully, such as correlation versus causation and avoiding claims of medical authority.

• Students interested in developing one of these topics into a structured research paper can apply to the Lumiere Research Scholar Program, which pairs high schoolers with PhD mentors over a 12-week independent research project.

1. Risk, Reward, and Adolescent Decision-Making

In this study, you'll use risk- and reward-based tasks to examine how teenagers balance priorities in decision-making. You'll design tasks for participants to complete (or choose to refrain), to examine which factors most influence their behavior. Ideas might include: Completing an optional time-consuming, complex, and/or boring task with a substantial reward for completion. An “all or nothing” challenge, where participants can opt into completing a difficult final task with the ability to double or lose all of their prizes based on their success. Offering the same challenge to two separate groups, where one group has the potential to win an additional reward, and the other may lose an existing reward. You’ll then analyze what tasks participants were most and least likely to complete, and what factors were the strongest and weakest motivating forces. Through this project, you’ll learn about prefrontal cortex development, impulsivity, and neurological reward systems.

2. Hand Dominance and Motor Speed

In this project, you’ll compare differences in motor skills when using one’s dominant or non-dominant hand. You’ll have participants complete a series of speed and coordination tasks, such as sorting objects or typing on a phone keyboard, in two trials, using their dominant hand in one and their non-dominant hand in the other. You’ll then evaluate performance differences between the hands. To add complexity, you can also analyze whether certain types of tasks have stronger performance gaps than others (e.g., those requiring more complex motions, or speed- versus accuracy-focused tasks) and whether results differ between right-handed and left-handed participants. Through this research, you’ll engage with neuroscience concepts in motor cortex specialization and hemispheric lateralization.

3. Blue Light Exposure and Sleep Quality

For this project, you’ll examine the impact of screen exposure on sleep quality and duration. You can pursue the project as an observational study, during which participants track their screen time and sleep patterns over a month. You could also implement an experimental approach, assigning participants who typically use their phones or computers soon before bed to stop tech use for a certain period before bed. If available, using smart sleep-measuring technology can supplement the somewhat subjective participant-reported information with quantifiable biological data. To add further depth to your study, you can introduce additional variables, such as technology type (smartphone versus computer), location (bedroom versus living room), or time (whether screen-time effects vary by participants’ bedtimes). You’ll learn about the neuroscience of melatonin suppression and circadian rhythms while studying an important question, as rates of technology usage increase.

4. Exercise and Short-Term Memory

Exercise is known to increase levels of brain-derived neurotrophic factor (BDNF), which promotes neuronal growth and improves learning, memory, and decision-making. In this project, you’ll evaluate the immediate cognitive effects of exercise on memory-related tasks. You’ll first have participants complete memory tasks before exercising — ensuring they haven’t exercised that day — to determine a baseline performance level. Participants will then complete light aerobic exercises, followed by a series of comparable memory tasks. You’ll then evaluate differences in performance and whether brief exercise has a meaningful impact on short-term memory. You can add complexity to the project by evaluating differences between individuals who exercise frequently versus rarely, or by altering the length and intensity of the exercise participants complete. You can also test whether confounding variables affect your results by conducting your experiment at different locations or times to see whether performance is affected by tiredness or distracting surroundings.

5. Digital Notifications and Attention Span

This research topic addresses a common trend in modern society — distraction by technological devices while working or studying — and its impact on neurological processes like working memory and sustained attention. You’ll have participants complete focus-based tasks with phone notifications and sounds turned on, then with notifications muted, to evaluate whether notifications negatively impact performance. The results of your study may be affected by participants’ awareness of your experimental approach, which may cause them to consciously or unconsciously avoid checking their notifications. You’ll also need to ensure that the number and frequency of notifications are fairly consistent across participants. As a result, carefully tailoring your explanation and execution of the study is important to avoid biased results. Another version of the project could address the presence of technology as a distracting force, monitoring whether performance changes when participants’ phones are screen-up (with notifications muted), screen-down, or in another room.

6. Handwriting vs Typing and Memory Retention

As computers and tablets become more common for taking notes in class, studying, and completing assignments, questions have arisen about how technology can be beneficial or detrimental to learning. This research examines the connections between memory consolidation and motor encoding, exploring whether writing out uniquely formed words promotes memory consolidation compared to typing on identical keys. You’ll randomly assign participants to typing and handwriting groups. You’ll then present each participant with an identical memory task, such as listening to an academic lecture while taking notes in their assigned format, and then take a quiz to assess their memory retention. You’ll then analyze differences in quiz performance amongst the groups. Through this project, you’ll learn about the hippocampus and the neuroscience of memory and its connections with sensorimotor learning.

7. Facial Recognition Speed Across Age Groups

Recent social and cultural trends, such as social media use, video calls, remote interaction, and COVID, can affect facial recognition capabilities. Younger populations see their friends’ faces frequently through online posts, but have spent several years during early developmental stages with masks limiting facial visibility in real life. On the other hand, remote work or longer-term exposure to friends and public figures may also impact older adults’ facial recognition skills. In this research topic, you’ll task individuals across age groups to identify familiar faces as quickly as possible. You can also show them unfamiliar faces labeled with names for a short period of time and test their recall. This project engages with the substantial changes in modern life while examining concepts in neuroscience, including visual processing, social cognition, and specialization within the fusiform face area.

8. Fear Conditioning Simulation

In this study, you’ll examine the development and impact of stress reactions through a fear conditioning process. This project teaches you about the amygdala, which plays a major role in emotional memory formation. You’ll develop an (ethical and mild) stressor that you’ll introduce while completing a task. One potential option is to introduce time pressure — an alarm rings every minute as participants complete a complex timed task. You can have participants begin by completing a version of the task with no time limit, followed by the experimental iteration, assessing performance and speed. You can then task them with repeating a third version of the task, without a time limit, but the alarm from the second round remains, and assess whether performance is closer to the baseline or to that in the stress-inducing round.

9. The Placebo Effect in Cognitive Tasks

This research study addresses the commonly studied placebo effect, but introduces more complexity to the process. The effect is traditionally associated with clinical trials and “official” research settings, whereas this study bypasses the impact of medical authority. You’ll recruit participants to study the effects of a “cognitive enhancer” (aka sugar pill), which you can identify as a caffeine pill or an imaginary supplement, on cognitive performance. As you won’t be claiming to be a medical professional or describing the “enhancer” as a pharmaceutical, this experiment can test the placebo effect in a more neutral setting. You’ll have participants complete analogous cognitive or academic tasks both before and after consuming the pill, and see whether performance is strengthened by the belief that they have received stronger cognitive abilities.

10. Bilingualism and Cognitive Flexibility

In this project, you’ll study potential correlations between multilingual capabilities and other forms of cognition, exploring whether the ability to manage two language systems has downstream effects on switching between disparate tasks. For your experimental design, you’ll develop multiple tasks or cognitive exercises and recruit both monolingual and bilingual participants. You’ll first have participants complete tasks separately to determine their performance baseline. In the experimental session, participants will complete comparable tasks, but be forced to switch back and forth between them before completing each one. Based on performance relative to baseline, you can then evaluate whether bilingual participants exhibit greater cognitive flexibility. This project draws on topics in neuroscience, including executive control networks, prefrontal cortex function, and attention and adaptability.

11. Sleep and Emotional Regulation in Adolescents

Research has demonstrated that poor sleeping habits or insufficient sleep can negatively affect one’s emotional well-being and stress regulation. As teenagers have been proven to require more sleep than adults, and are more prone to mood swings as they undergo hormonal changes during puberty, this topic examines how sleep disruptions specifically impact emotional regulation in adolescents. You’ll recruit participants willing to track their sleep habits with a smartwatch or similar device, specifically monitoring sleep stages, sleep quality, and sleep duration, including naps if relevant. Each day, you’ll task participants with filling out a mood rating form measuring anxiety, sadness, optimism, stress management, and/or other factors. Note that, as emotional disorders like anxiety and depression can cause sleep irregularities, it’s important to be aware that data associating poor sleep with challenges in emotional regulation may not be a causal link.

12. Cognitive Load and Decision Accuracy

In this research study, you’ll examine cognitive load and executive function. In short, your research will examine how competing and increasing demands impact overall cognitive abilities. You’ll have participants complete progressively more challenging tasks, increasing their ongoing cognitive load, while tracking their accuracy and speed. You’ll use participants’ performance data to analyze whether increased cognitive load leads to higher error rates, thus determining its impact on working memory and focus.

13. Mirror Drawing Task and Motor Learning

This research topic addresses motor learning and implicit memory systems through a participant-based experimental study. You’ll have each participant draw shapes presented to them, only seeing their hand and drawing in a mirror. Over repeated trials, you’ll measure changes in the accuracy of the drawing and the time needed to draw the same shape over time. You can consider introducing new and more complex shapes as a final step, evaluating whether the improvement in mirror drawing applies to unfamiliar applications or is limited to practiced tasks.

14. Reaction Time under Emotional Stimuli

In this research topic, you’ll study the impact of emotion on cognitive processing and attention. You’ll show participants a fast-paced series of images, during which they must click on an accurate label or complete another task as quickly as possible after viewing each image. You’ll randomly insert images with neutral (e.g., trees, furniture), positive (e.g., cute animals), and stressful (e.g., natural disaster) emotional associations, then measure whether participants’ reaction time is impacted by the emotional valence of the stimulus.

15. Mindfulness and Stress Markers

For this project, you can connect neuroscience to mental health by studying the potential effects of mindfulness practices on stress-regulation skills. You’ll use equipment such as a heart monitor or a smartwatch to track your pulse and other physiological indicators. You’ll then guide participants through a meditation session and measure changes (or lack thereof) in stress markers such as pure heart rate or heart rate variability. Based on the degree of change, you can evaluate whether these practices are physiologically effective in stress reduction. This study engages with brain regions such as the amygdala and prefrontal cortex, connecting neuroscience with psychology and physiology.
