The thalamocortical contribution to epilepsy

Bulletin of Mathematical Biology, 1991
The experimental literature has dealt intensively with the cortical contribution to epilepsy. Possibly because of the direction of technological advance, much less attention has been paid to the role of other structures. A model which emphasizes the role of some of those non-cortical structures, specifically that of thalamocortical modulation of ...

Abnormal Thalamocortical Circuit in Adolescents With Early-Onset Schizophrenia.

Journal of the American Academy of Child and Adolescent Psychiatry, 2020
OBJECTIVE Thalamic circuit imbalance characterized by increased sensorimotor-thalamic connectivity and decreased prefrontal-thalamic connectivity has been consistently observed in adult-onset schizophrenia (AOS), though it is unclear if this pattern is ...

A thalamocortical top-down circuit for associative memory

Science, 2020
Higher-order thalamus input to the cortex Sensory information can only be used meaningfully in the brain when integrated with and compared with internally generated top-down signals.

Thalamocortical Synapses

2023
Abstract Thalamocortical (TC) synapses play important roles in relaying information about internal states and the external world to the cortex. Therefore, it is imperative to understand how variations in their morphological, connective, and functional properties influence signal transfer and processing.

An Activation Likelihood Estimate Meta-analysis of Thalamocortical Dysconnectivity in Psychosis.

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2019
BACKGROUND Thalamocortical dysconnectivity is hypothesized to underlie the pathophysiology of psychotic disorders, including schizophrenia and bipolar disorder, and individuals at clinical high risk.

Thalamocortical Interactions

1995
AbstractAll sensory information, except for olfaction, passes through the synaptic network of the thalamus just before reaching the cerebral cortex, suggesting that the thalamus may exert a powerful influence on sensory and motor processing. However, the connection is not unidirectional: layer VI of the cerebral cortex contributes up to 50% of the ...

Thalamocortical connections in newborn mice

Journal of Comparative Neurology, 1984
AbstractThalamocortical axons reach the developing neocortex and become distributed within the cortical subplate during the third week of gestation. The present study is an analysis of the organization of connections that link thalamus and cortical subplate (corresponding to future layers V and VI) at birth.

Functional organization of thalamocortical relays

Journal of Neurophysiology, 1996
The thalamus has long been seen as responsible for relaying information on the way to the cerebral cortex, but it has not been until the last decade or so that the functional nature of this relay has attracted significant attention. Whereas earlier views tended to relegate thalamic function to a simple, machine-like relay process, recent research ...

Thalamocortical patches in auditory neocortex

Brain Research, 1993
Thalamocortical afferents to the primary auditory cortex of the rabbit were labeled by the iontophoretic injection of the anterograde tracers PHA-L or biocytin into the ventral division of the medial geniculate body (vMGB). Single injections of either tracer into the vMGB labeled multiple "patches" of afferent axons in lamina III/IV of the ipsilateral ...
