How the brain learns hidden sequences

Implicit serial learning

['FUNDING_R01'] · COLUMBIA UNIVERSITY HEALTH SCIENCES · NIH-11296898

This work looks at how the brain learns and uses hidden sequences to guide choices, with the goal of improving understanding of memory and thinking problems seen in Alzheimer's disease and autism.

What this research studies

This research uses trained nonhuman primates, detailed behavior tests, and computer models to study how hidden patterns are learned and used to make decisions. Scientists will record single-neuron activity in specific brain areas (dorsolateral and ventromedial prefrontal cortex and dorsal striatum) while animals perform sequence tasks. They will also measure how brain chemicals like acetylcholine and dopamine change during learning. The goal is to link basic brain circuits to the kinds of memory and decision-making problems that show up in Alzheimer’s and autism.

Who could benefit from this research

Good fit: People living with Alzheimer's disease, mild cognitive impairment, or autism spectrum disorder who are interested in research into the brain mechanisms behind learning might find this work relevant to future clinical advances.

Not a fit: Patients seeking immediate treatments or those with conditions unrelated to memory, learning, or decision-making are unlikely to receive direct benefit from this preclinical research.

Why it matters

Potential benefit: If successful, the findings could point to new ways to detect or eventually treat memory and decision-making problems in Alzheimer's disease and related conditions.

How similar studies have performed: Previous animal and human imaging studies have linked these brain regions to learning and decision-making, but combining behavior, single-cell recordings, and neuromodulator measures in this way is relatively novel.
