Thalamic inputs of cells in sensory cortices are outnumbered by local connections. Thus, it was suggested that robust sensory response in layer 4 emerges due to synchronized thalamic activity. To ...

A growing body of research is converging on specific brain regions and networks that appear to generate conscious experience, from dreaming to waking awareness. Multiple independent lines of evidence ...

One powerful type of transformation comes from interactions between excitatory neurons that carry data to the neocortex and inhibitory neurons of the thalamic reticular nucleus, or TRN, that regulate ...

Using direct, intracranial brain recordings in humans, a new study finds that the thalamus, a small region located deep within the brain, plays a pivotal role in conscious perception. According to the ...

The thalamus is a 'Grand Central Station' for sensory information coming to our brains. Almost every sight, sound, taste and touch travels to our brain's cortex via the thalamus. Researchers now ...

A series of recent brain-imaging studies has begun to explain a central mystery of the psychedelic experience: why people on psilocybin report that memories seem to blend with what they are actually ...

A 55 year-old hypertensive man developed a headache, nausea and vomiting, associated with left sided numbness which slowly worsened over 2 hours. He later became lethargic. His neurological exam ...

Researchers identify that the brain's sensory checkpoint (TRN) undergoes a molecular "upgrade" in adulthood for high-resolution perception.

A 52 year-old hypertensive man developed a headache, nausea and vomiting, associated with right sided numbness which slowly worsened 30 minutes. He then developed right sided weakness followed by a ...
