Long-term Depression01:05

Long-term Depression

33.2K
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.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants

394
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Cognitive Dissonance

36.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Depression: Overview

824
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Area of Science:

  • Psychiatry
  • Cognitive Neuroscience

Background:

  • Depression is a common psychiatric disorder impacting mood and cognition.
  • Cognitive theories suggest biases contribute to depression's development and recurrence.
  • Previous models are updated by recent pharmacological, neuroimaging, and neurocognitive research.

Purpose of the Study:

  • To review evidence on cognitive dysfunctions in depression.
  • To integrate knowledge on cognitive aspects, their biological underpinnings, and treatment implications.
  • To present a reformulated cognitive theory of depression.

Main Methods:

  • Literature review synthesizing findings from various research domains.
  • Analysis of pharmacological, neuroanatomical, and genetic studies related to cognitive function in depression.
  • Integration of neuroimaging and neurocognitive data.

Main Results:

  • Cognitive dysfunctions are evident in depression.
  • Pharmacological, neuroanatomical, and genetic factors are associated with these cognitive deficits.
  • A reformulated cognitive theory integrates these findings.

Conclusions:

  • The updated cognitive theory offers a framework for understanding depression.
  • This framework guides future research for risk identification and improved treatment outcomes.
  • Further investigation is needed to minimize recurrence and maximize long-term benefits for patients.
