Study Notes
Neural Mechanism of Decision Making in Monkey Experiment
- The experiment involves a monkey making decisions based on the direction of motion of random dots.
- The reaction time (RT) version of the task allows the subject to control the viewing duration and make eye movements to indicate decisions.
- The gray patch in the task indicates the location of the response field (RF) of a Lateral Intraparietal area (LIP) neuron.
- Monkey's performance and mean reaction time (RT) are shown to vary with motion strength.
- The response of a single LIP neuron is illustrated for correct choices at two motion strengths (6.4% and 51.2%).
- Spike rasters and response histograms are used to depict the neuron's response aligned with the monkey's eye movement response.
- The trial rasters are sorted by reaction time (RT).
- The average response of LIP neurons during the experiment is shown.
- The figure depicts the neural mechanism of decision making in a monkey during a random-dot motion direction discrimination experiment.
- The experiment involves analyzing the response of LIP neurons to understand the neural basis of decision making in the monkey.
- The monkey's performance and reaction times are correlated with the motion strength in the experiment.
- The experiment provides insights into the neural mechanisms underlying decision making in monkeys.
