    THE PROGRAM

  • Almond-shaped, the amygdala takes all of the information from the part of your brain called the thalamus relay station and pushes it to the cortex—the part of the brain that helps you make decisions, such as running out of a burning home.

  • The thalamus is a tiny structure, about 1 centimeter in length, that sits on top of the brain stem deep in the center of the brain.

    Born to Believe

  • Since the thalamus is a key relay of neuronal information in the brain, I have hypothesized that the asymmetry might be associated with long-term meditation processes.

    Born to Believe

  • Described as bursts of fast brain rhythms that punctuate the otherwise slow-wave patterns characteristic of sleep, these spindle rhythms originate out of the thalamus, which is located at the top of the brainstem and is known to affect motor control, and receive and relay auditory, somatosensory and visual sensory signals.

  • ...my increasing tolerance to large doses and my increasing need for the drug have led them to consider Pennybacker's idea ('Management of intractable pain', Proceedings of the Royal Society of Medicine, 1963, 56, p. 191) of leucotomy, meddling with the thalamus or with the frontal lobe.
