Cholinergic fibers from the brainstem and basal forebrain innervate the medial prefrontal cortex (mPFC) modulating neuronal activity and synaptic plasticity responses to hippocampal inputs."
OLM interneurons differentially modulate CA3 and entorhinal inputs to hippocampal CA1 neurons"
Oct 09, 2012
The vast diversity of GABAergic interneurons is believed to endow hippocampal microcircuits with the required flexibility for memory encoding and retrieval. However, dissection of the functional roles of defined interneuron types has been hampered by the lack of cell-specific tools. We identified a precise molecular marker for a population of hippocampal GABAergic interneurons known as oriens lacunosum-moleculare (OLM) cells. "
Psychosis has various causes, including mania and schizophrenia. Since the differential diagnosis of psychosis is exclusively based on subjective assessments of oral interviews with patients, an objective quantification of the speech disturbances that characterize mania and schizophrenia is in order. In principle, such quantification could be achieved by the analysis of speech graphs. A graph represents a network with nodes connected by edges; in speech graphs, nodes correspond to words and edges correspond to semantic and grammatical relationships."

If trajectory and direction of motion are known beforehand, the detection of a moving object at future positions might be facilitated. In agreement, primary visual cortical neurons close to the visual field's midline seem to anticipate movements and shapes of objects which could potentially cross from one visual hemifield into the other."
Hierarchical structure with nested nonlocal dependencies is a key feature of human language and can be identified theoretically in most pieces of tonal music."

Synchronization through nonreciprocal connections in a hybrid hippocampus microcircuit."

Synchronization among neurons is thought to arise from the interplay between excitation and inhibition; however, the connectivity rules that contribute to synchronization are still unknown."
