The Contribution of Thalamocortical Core and Matrix Pathways to Sleep Spindles. [PDF]
, 2016 Sleep spindles arise from the interaction of thalamic and cortical neurons. Neurons in the thalamic reticular nucleus (TRN) inhibit thalamocortical neurons, which in turn excite the TRN and cortical neurons.

Thalamocortical Circuit Motifs: A General Framework.
Neuron, 2019 The role of the thalamus in cortical sensory transmission is well known, but its broader role in cognition is less appreciated. Recent studies have shown thalamic engagement in dynamic regulation of cortical activity in attention, executive control, and ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]
, 2001 The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Frontiers in Integrative Neuroscience, 2011 It is known that the thalamocortical loop plays a crucial role in the encoding of sensory-discriminative features of painful stimuli. However, only a few studies have addressed the changes in thalamocortical dynamics that may occur after the onset of ...

The role of inhibitory feedback for information processing in thalamocortical circuits [PDF]
, 2006 The information transfer in the thalamus is blocked dynamically during sleep, in conjunction with the occurence of spindle waves. As the theoretical understanding of the mechanism remains incomplete, we analyze two modeling approaches for a recent ...

Cell Reports, 2017 The rodent somatosensory cortex includes well-defined examples of cortical columns—the barrel columns—that extend throughout the cortical depth and are defined by discrete clusters of neurons in layer 4 (L4) called barrels.

Excitability of the motor cortex in patients with migraine changes with the time elapsed from the last attack [PDF]
, 2017 BACKGROUND: Motor-evoked potentials (MEPs) produced by single-pulse transcranial magnetic stimulation (TMS) of the motor cortex can be an objective measure of cortical excitability.

Consciousness CLEARS the Mind [PDF]
, 2007 A full understanding of consciouness requires that we identify the brain processes from which conscious experiences emerge. What are these processes, and what is their utility in supporting successful adaptive behaviors?

Thalamocortical Anatomical Connectivity in Schizophrenia and Psychotic Bipolar Disorder.
Schizophrenia bulletin, 2020 BACKGROUND Anatomical connectivity between the thalamus and cortex, including the prefrontal cortex (PFC), is abnormal in schizophrenia. Overlapping phenotypes, including deficits in executive cognitive abilities dependent on PFC-thalamic circuitry ...

Long-term deficits in cortical circuit function after asphyxial cardiac arrest and resuscitation in developing rats [PDF]
, 2017 Cardiac arrest is a common cause of global hypoxic-ischemic brain injury. Poor neurologic outcome among cardiac arrest survivors results not only from direct cellular injury but also from subsequent long-term dysfunction of neuronal circuits.
