TL;DR: This review emphasizes the fact that the nervous system components governing circadian rhythmicity constitute a specialized subdivision of the vertebrate visual system, and certain transneuronal tracers label only the circadian visual system.

TL;DR: In the adult brain the molecules constituting the 'perineuronal nets of matrix' could serve as recognition molecules between certain neurons and their surrounding cells and participate in the selection and consolidation of their relationship.

TL;DR: The piracetam-like nootropics are capable of achieving reversal of amnesia induced by scopolamine, electroconvulsive shock and hypoxia and much evidence points in the direction of a modulated ion flux by, e.g., potentiated calcium influx through non-L-type voltage-dependent calcium channels, potentiated sodium influx through alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor gated channels or

TL;DR: The present paper outlines what is known about the anatomical, biochemical and physiological changes introduced by naris occlusion in order to lay a framework for further work.

TL;DR: The present review concerns itself with four major neuropeptide systems--enkephalin, dynorphin, tachykinins and neurotensin--and it summarizes neuroanatomical and functional studies as well as emphasizing regulatory interactions between neurotransmitters and neuropepeptides at the level of neuropePTide gene expression.

TL;DR: It is argued that alterations in these pathways are ideal candidates for producing the behaviors which occur during psychosis and that future considerations of the circuitry underlying psychoses need to include this highly important but relatively neglected system.

TL;DR: The present cladistic analysis found that two corresponding, fundamental divisions of the dorsal pallium were present in captorhinomorph amniotes and were expanded relative to their condition in anamniotes.

TL;DR: The differential and selective localizations of CBPs in the spinal cord suggest a role for these proteins in spinal nociceptive processing, visceral regulation and dorsal column sensory pathways.

TL;DR: The new hypothesis holds that the dorsal thalamus comprises two basic divisions--the collothalamus and the lemnothalamus--that receive their predominant input from the midbrain roof and (plesiomorphically) from lemniscal pathways, including the optic tract, respectively.

TL;DR: By reviewing the literature, the pedunculopontine tegmental nucleus seems to be involved in attentional and possibly also in learning processes, and could be mediated by influencing cortical function via the thalamus, basal forebrain and basal ganglia.

TL;DR: This work has shown that calcium-activated non-selective channels in cardiac myocytes, pancreatic acini and neuroblastoma are capable of producing maintained depolarization of neurons, and this property endows upon CAN channels an important role in both physiological functions and pathological processes of the nervous system.

TL;DR: It is suggested that experience-dependent changes in neural connectivity occur in many different brain systems and particular brain structures, such as the hippocampus, do not play any uniquely important role in experience- dependent behavior.

TL;DR: Several of the most widely studied models of synaptic-level neuroplasticity are considered including alterations in response properties of two types of invertebrate sensory neurons, long-term potentiation (LTP) in mammalian hippocampus and cortex, and ocular dominance shifts in cat visual cortex.
