Feedback Inhibition00:46

Feedback Inhibition

57.1K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Long-term Depression

33.3K
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.

Abnormal Proliferation02:23

Abnormal Proliferation

5.2K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Freezing Point Depression and Boiling Point Elevation

40.1K
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...

Depressants01:28

Depressants

436
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...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Science

Background:

  • Depressive disorder significantly impacts global health, quality of life, and occupational function.
  • Cognitive distortions are central to psychological models of depression, with cognitive problems noted in diagnostic criteria.
  • Aberrant sensitivity to positive and negative feedback is a key neurocognitive mechanism in depression.

Purpose of the Study:

  • To review recent advances in preclinical modeling of aberrant feedback sensitivity in depression.
  • To evaluate the translational value of the probabilistic reversal-learning (PRL) task for studying feedback sensitivity.
  • To identify future research directions, including cognitive biomarkers and personalized treatment targets for depression.

Main Methods:

  • Summarizing recent advances in understanding neurocognitive mechanisms and neurobiological substrates of aberrant feedback sensitivity.
  • Employing a combination of behavioral, neurochemical, neuroanatomical, and pharmacological approaches.
  • Evaluating the probabilistic reversal-learning (PRL) task as a translational tool.

Main Results:

  • Recent progress in understanding the neurocognitive mechanisms and neurobiological underpinnings of feedback sensitivity in depression.
  • The probabilistic reversal-learning (PRL) task demonstrates translational value for investigating feedback sensitivity across species.
