Elucidating memory in the brain via single-cell transcriptomics

Area of Science:

• Neuroscience
• Molecular Biology
• Genomics

Background:

• Understanding the neural basis of memory is a fundamental challenge in neuroscience.
• The hippocampus and amygdala are critical brain regions for memory formation and processing.
• Current methods offer limited resolution for dissecting complex memory circuits.

Purpose of the Study:
