In addition to the interesting implications for our understanding of microcircuit dynamics of memory, this paves the way to developing new avenues that could one day be used for treating patients with chronic memory impairment.

Although non-invasive methods to explore brain function in humans such as functional imaging and EEG / MEG have been informative regarding the potential role of a given brain area in a particular cognitive function, they lack the necessary temporal and spatial resolution to study brain microcircuits.

It has been a longstanding hypothesis that alterations in the microcircuit of the prefrontal cortex and / or in its connectivity with the rest of the brain may be at the core of many of these disorders.

Novel MRI acquisition and analysis methods are paving the way for in - vivo assessment of the layer - specific microcircuits first targeted by neurodegenerative diseases.

Our studies reveal the existence of two segregated excitatory synaptic microcircuits that propagate homeostatic sleep information from different populations of intrinsic MB «Kenyon cells» (KCs) to specific sleep - regulating MBONs: sleep - promoting KCs increase sleep by preferentially activating the cholinergic MBONs, while wake - promoting KCs decrease sleep by preferentially activating the glutamatergic MBONs.

These studies reveal for the first time specific functional connections between subsets of KCs and particular MBONs and establish the identity of synaptic microcircuits underlying transmission of homeostatic sleep signals in the MB.

These studies reveal a dopaminergic sleep control mechanism that likely operates by modulation of KC - MBON microcircuits.
