Thalamocortical connectivity
WebBackground and purpose: Thalamocortical connections play a crucial role in complex cognitive functioning, and several neuropsychiatric disorders may involve aberrant … Thalamocortical radiations have been researched extensively in the past due to their relationship with attention, wakefulness, and arousal. Past research has shown how an increase in spike-and-wave activity within the TC network can disrupt normal rhythms involved with the sleep-wakefulness cycle, ultimately causing absence seizures and other forms of epileptic behavior. Burst firing within a part of the TC network stimulates GABA receptors within the thalamus causin…

Each cortical region of interest was connected to distinct, largely nonoverlapping regions of the thalamus ( Figure 1 ). The present results are virtually identical to those reported in previous studies using the same method in healthy adults (14, 15, 23 ).
WebRecurrent thalamo-cortical resonance is an observed phenomenon of oscillatory neural activity between the thalamus and various cortical regions of the brain. It is proposed by Rodolfo Llinas and others as a theory for the integration of sensory information into the whole of perception in the brain.
