Interactions between hippocampus and visceral organs in sleep and wakefulness

This study investigates synchronization between hippocampal activity and visceral signals during sleep and wakefulness in cats, finding that interoceptive signals influence hippocampal dynamics in both states.

Nucleus Basalis of Meynert as a DBS target

This study investigates the effects of different deep brain stimulation patterns on nucleus basalis of Meynert in mice, finding that nested stimulation preserves gamma activity while tonic stimulation suppresses broad-band cortical activity.

A neural framework for spontaneous development of orientation selectivity in the primary visual cortex

This paper demonstrates a computational model showing how orientation selectivity in V1 develops through retinal activity and Hebbian plasticity without external input.

Dynamics of coherent activity between cortical areas defines a two-stage process of selective attention

The paper investigates how coherent neural activity between brain regions supports working memory and top-down attention during visual pattern matching tasks in macaques.

Diversity of feature selectivity in macaque visual cortex arising from limited number of broadly-tuned input channels

The paper shows that the diversity of orientation selectivity in macaque visual cortex arises from a limited number of broadly-tuned thalamic input channels.
