Abstract

The claustrum is a long, band-like grey matter structure situated in the ventrolateral telencephalon of most, if not all, mammalian brains. Due to its shape and close proximity to white matter structures and insular cortex, the anatomy and behavioral relevance of the claustrum have proven difficult to study. As a result, disagreements in the literature exist over ontogeny, phylogeny, anatomical boundaries, and connectivity. Despite this, it is generally regarded that the claustrum contains excitatory projection neurons that reciprocally connect to most regions of the cerebral cortex, a feature that has fostered varying hypotheses as to its function. These hypotheses propose multisensory integration, coordination of cortical activity for the generation of conscious percepts, or saliency filtration. The articles of this e-book consider the historical and recent highlights in claustrum structure, hodology, and function and seek to provide a compelling way forward for this “hidden” nucleus.

Abstract

It is in general well appreciated that the cortical interneurons play various important roles in cortical neuronal networks both in normal and pathological states. Based on connectivity pattern, developmental, morphological and electrophysiological properties, distinct subgroups of GABAergic interneurons can be differentiated in the neocortex as well as in the hippocampal formation. In this E-Book, we are focusing our attention on inhibitory interneurons expressing calcium-binding protein calretinin (CR). The aim of the E-Book is to consolidate the knowledge about this interneuronal population and to inspire further research on the function and malfunction of these neurons, which – functionally – seem to stand "at the top of the pyramid" of cortical interneuronal types.
