Patchwork-Type Spontaneous Activity in Neonatal Barrel Cortex Layer 4 Transmitted via Thalamocortical Projections

open access: yesCell Reports, 2018
Summary: Establishment of precise neuronal connectivity in the neocortex relies on activity-dependent circuit reorganization during postnatal development; however, the nature of cortical activity during this period remains largely unknown.

A cerebellar-thalamocortical pathway drives behavioral context-dependent movement initiation

open access: yesNeuron, 2021
Summary Executing learned motor behaviors often requires the transformation of sensory cues into patterns of motor commands that generate appropriately timed actions.

Cholecystokinin modulates age-dependent thalamocortical neuroplasticity [PDF]

open access: yeseLife
The thalamocortical pathways exhibit neuroplasticity not only during the critical period but also in adulthood. In this study, we investigated how cholecystokinin (CCK) modulates age-dependent thalamocortical plasticity.

Computational modeling of resistance to hormone-mediated remission in childhood absence epilepsy [PDF]

open access: yesFrontiers in Computational Neuroscience
Childhood absence epilepsy (CAE) often resolves during adolescence, a period marked by hormonal and neurosteroid changes associated with puberty. However, remission does not occur in all individuals.

Thalamocortical Axonal Activity in Motor Cortex Exhibits Layer-Specific Dynamics during Motor Learning

open access: yesNeuron, 2018
The thalamus is the hub through which neural signals are transmitted from the basal ganglia and cerebellum to the neocortex. However, thalamocortical axonal activity during motor learning remains largely undescribed.

Thalamocortical Connectivity and Microstructural Changes in Congenital and Late Blindness [PDF]

open access: yesNeural Plasticity, 2017
There is ample evidence that the occipital cortex of congenitally blind individuals processes nonvisual information. It remains a debate whether the cross-modal activation of the occipital cortex is mediated through the modulation of preexisting ...

Thalamocortical Mechanisms Underlying Real and Imagined Acupuncture

open access: yesBiomedicines, 2023
Both acupuncture and imagery have shown potential for chronic pain management. However, the mechanisms underlying their analgesic effects remain unclear.

Ultrafast (400 Hz) network oscillations induced in mouse barrel cortex by optogenetic activation of thalamocortical axons

open access: yeseLife, 2023
Oscillations of extracellular voltage, reflecting synchronous, rhythmic activity in large populations of neurons, are a ubiquitous feature in the mammalian brain, and are thought to subserve important, if not fully understood roles in normal and abnormal

Cooperative thalamocortical circuit mechanism for sensory prediction errors

open access: yesbioRxiv, 2023
The brain functions as a prediction machine, utilizing an internal model of the world to anticipate sensations and the outcomes of our actions. Discrepancies between expected and actual events, referred to as prediction errors, are leveraged to update ...

Acute and Long-Term Circuit-Level Effects in the Auditory Cortex After Sound Trauma

open access: yesFrontiers in Neuroscience, 2021
Harmful environmental sounds are a prevailing source of chronic hearing impairments, including noise induced hearing loss, hyperacusis, or tinnitus. How these symptoms are related to pathophysiological damage to the sensory receptor epithelia and its ...
