Systems Neuroscience Lab

Projects

Our research program aims to determine the neural basis for spatial cognition, decision-making, and episodic memory. Recent projects have focused primarily on examination of multiple single-unit recordings made in freely behaving animals. Our most recent work concerns recordings made in the parietal cortex, hippocampus, subiculum, and premotor cortex in rats performing either a multiple-T working memory task or executing traversals of differently shaped spiral paths. One new project will examine the activity patterns of basal forebrain neurons during performance of a task demanding dynamic allocation of attentional resources.

Databyte - Hippocampus




Databyte - Parietal Cortex




Databyte - Basal Forebrain




Center plot shows the color-mapped firing rate of 600 basal forebrain neurons categorized according to their times of peak activity across the stages of a selective attention task. Surrounding plots show the color-mapped firing rates of individual neurons across multiple trials, highlighting the reliability of task-phase specific activity and heterogeneity, across neurons, of such activity. Category 1 neurons responded to light stimuli. Category 4 neurons during movement to the attended light source. Category 15 neurons fire most during nosepoke at the light source. Category 17 neurons are reward responsive. The data suggest that the basal forebrain coordinates shifts in attention appropriate to each task phase.
