Subanesthetic ketamine treatment promotes abnormal interactions between neural subsystems and alters the properties of functional brain networks [PDF]

open access: yes, 2014
Acute treatment with subanesthetic ketamine, a non-competitive N-methyl-D-aspartic acid (NMDA) receptor antagonist, is widely utilized as a translational model for schizophrenia. However, how acute NMDA receptor blockade impacts on brain functioning at a

A Diagnosis Model of Typhoon‐Related Post‐Traumatic Stress Disorder Based on Fixel‐Based Analysis in Machine Learning

open access: yesBrain and Behavior, Volume 16, Issue 4, April 2026.
Fixel‐based analysis revealed discrete patterns of white‐matter disruption in typhoon‐related PTSD, particularly affecting the frontopontine, middle longitudinal, and thalamo‐premotor pathways. Integrating these tract‐specific signatures into machine‐learning models allowed robust discrimination between PTSD and trauma‐exposed controls, suggesting ...

Thalamic Inhibition: Diverse Sources, Diverse Scales. [PDF]

open access: yes, 2016
The thalamus is the major source of cortical inputs shaping sensation, action, and cognition. Thalamic circuits are targeted by two major inhibitory systems: the thalamic reticular nucleus (TRN) and extrathalamic inhibitory (ETI) inputs.

The pathways connecting the hippocampal formation, the thalamic reuniens nucleus and the thalamic reticular nucleus in the rat

open access: yesJournal of Anatomy, 2008
AbstractMost dorsal thalamic nuclei send axons to specific areas of the neocortex and to specific sectors of the thalamic reticular nucleus; the neocortex then sends reciprocal connections back to the same thalamic nucleus, directly as well indirectly through a relay in the thalamic reticular nucleus.

Global and Regional Vigilance: Are There Two Types of Local Sleep?

open access: yesBrain and Behavior, Volume 16, Issue 4, April 2026.
The term local sleep as it is used in the literature is confusing and probably consists of two types of brain states. The first one originates from increased activity in certain cortical areas during waking, resulting in increased activity in the slow‐waves range in that same area during subsequent NREM sleep. The second one consists of local states in

Upregulated and Hyperactivated Thalamic Connexin 43 Plays Important Roles in Pathomechanisms of Cognitive Impairment and Seizure of Autosomal Dominant Sleep-Related Hypermotor Epilepsy with S284L-Mutant α4 Subunit of Nicotinic ACh Receptor

open access: yesPharmaceuticals, 2020
To understand the pathomechanism and pathophysiology of autosomal dominant sleep-related hypermotor epilepsy (ADSHE), we studied functional abnormalities of glutamatergic transmission in thalamocortical pathway from reticular thalamic nucleus (RTN ...

THE DIFFERENTIAL EXPRESSION PATTERNS OF MESSENGER RNAs ENCODING NOGO-A AND NOGO-RECEPTOR IN THE RAT CENTRAL NERVOUS SYSTEM [PDF]

open access: yes, 2005
Nogo-A and Nogo-receptor have been considered to play pivotal roles in controlling axonal regeneration and neuronal plasticity. We investigated the total distribution of Nogo-A and Nogo-receptor mRNAs in the adult rat central nervous system using in situ

Nps‐Expressing Neurons Receive Extensive Input From Auditory Brainstem Nuclei

open access: yesJournal of Comparative Neurology, Volume 534, Issue 4, April 2026.
Nps‐expressing neurons receive input from auditory brainstem nuclei, with additional afferents from the reticular formation, midbrain, hypothalamus, and extended amygdala. While rabies retrograde labeling in the cerebral cortex was sparse, cholera toxin beta (CTb) revealed copious input, and anterograde tracing identified many axons and boutons ...

Selectively driving cholinergic fibers optically in the thalamic reticular nucleus promotes sleep

open access: yeseLife, 2016
Cholinergic projections from the basal forebrain and brainstem are thought to play important roles in rapid eye movement (REM) sleep and arousal. Using transgenic mice in which channelrhdopsin-2 is selectively expressed in cholinergic neurons, we show ...
