Scientists use ultrasound to jump-start a man's brain after coma

A 25-year-old man recovering from a coma has made remarkable progress following a treatment at UCLA to jump-start his brain using ultrasound. The technique uses sonic stimulation to excite the neurons in the thalamus, an ...

Brain 'relay' also key to holding thoughts in mind

Long assumed to be a mere "relay," an often-overlooked egg-like structure in the middle of the brain also turns out to play a pivotal role in tuning-up thinking circuity. A trio of studies in mice funded by the National Institutes ...

Thalamus found to add contextual information to visual signals

The thalamus not only relays visual signals from the eye to the visual cortex as previously thought, but also conveys additional, contextual information. Integrating these different signals is essential to understand and ...

Rewriting the brain pathway for consciousness

With a finding that will "rewrite neuroanatomy textbooks," University of Iowa neurologist Aaron Boes, MD, Ph.D., and his colleagues show that the thalamus is not a critical part of the brain pathway involved in keeping humans ...
