Neural Regulation

34.8K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Higher Mental Functions of the Brain: Language

6.0K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Long-term Depression

2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Lateralization01:28

Lateralization

1.4K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Summary

Understanding cognitive impairment requires mapping brain functions. Researchers integrate lesion analysis with cognitive deficit data to clarify complex brain-behavior relationships in neurological disorders.

Area of Science:

  • Neuroscience
  • Cognitive Neurology

Context:

  • Cognitive impairment is a key neurological finding, but localizing specific cognitive functions is complex.
  • Individual variability in cognitive abilities and brain networks, alongside hierarchical cognitive organization, complicates functional mapping.
  • Studying brain-behavior relationships traditionally involved focal lesions (e.g., stroke, tumors), but neuroimaging now allows investigation in neurodegenerative diseases.

Purpose:

  • To elucidate the intricate relationship between brain structure/function and cognitive performance.
  • To explore how brain atrophy distribution relates to cognitive deficits in neurodegenerative conditions.
  • To refine methods for understanding brain-behavior links by integrating lesion and deficit analyses.

Summary:

  • Cognitive functions are challenging to localize due to individual differences and complex brain networks.
