  • perfusion
  • 2 In animal studies, both options have been explored analyzing the fluorescence of different contrast agents, while in humans mostly the optical contrast agent indocyanine green (ICG) has been employed to assess brain perfusion by non-invasive optical approaches. (spiedigitallibrary.org)
  • amygdala
  • We focus on the hypothalamus, hippocampus, amygdala, nucleus accumbens, prefrontal and orbitofrontal cortex, key brain regions that not only modulate emotions and cognition but also the response to stress itself, and discuss disorders like depression, post-traumatic stress disorder, Cushing syndrome and dementia.

  • regions
  • In this review, we discuss recent results that have identified important brain regions involved in the incubation of drug craving, as well as evidence for the underlying cellular mechanisms. (nih.gov)
  • Cortical Sensory Modulation of Hippocampal Activity and Spatial Representation - Investigating how different inputs from different brain regions related to space and senses work together to form memories of experiences. (mcknight.org)
  • complex
  • However, the human brain is complex, enigmatic, and far more advanced than computers in many ways-for example, given that unconscious precursors have been found to precede volitional motor movement by as much as several hundred milliseconds (Shibasaki & Hallett, 2006), one might conclude by conventional models that parts of the brain are able to travel backward through time-a manifestly ludicrous conclusion.

  • effects
  • Virtually every aspect of our body and brain can be influenced by stress and although its effects are partly mediated by powerful corticosteroid hormones that target the nervous system, relatively little is known about when, and how, the effects of stress shift from being beneficial and protective to becoming deleterious.

  • early
  • But some differences are also seen extremely early in development, which may suggest that biology also plays a role. (nytimes.com)
  • larger
  • For example, the average man's cerebrum (the area in the front of the brain concerned with higher thinking) is 9 percent larger than the average woman's. (nytimes.com)
  • analysis
  • This year's Scholars tackle brain biology across multiple levels of analysis in a variety of model organisms," says Martin. (mcknight.org)
  • lead
  • Liver failure or congenital defects can lead to a build-up of ammonia in the brain of mammals resulting in life-threatening swelling, convulsions and comas. (scienceblogs.com)
