Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

66.4K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

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.

Freezing Point Depression and Boiling Point Elevation

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

462
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...

Depression: Overview

925
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,...

  • To investigate the potential of gut microbiota modulation as a therapeutic strategy for depression.

Main Methods:

  • Review of studies investigating the gut microbiota and its connection to the brain-gut axis in depression.
  • Analysis of research on the impact of gut microbiota dysbiosis on mental health.

Main Results:

  • Gut microbiota dysfunction is implicated as a potential direct cause of depression.
  • Abnormalities in the microbiota-gut-brain axis are associated with mental disorders.
  • Correcting gut microbiota disturbances may alleviate depressive symptoms.

Conclusions:

  • Gut microbiota modulation is an emerging area of research for mental disorder treatment.
  • Maintaining or restoring healthy gut microbiota is crucial for the prevention and therapy of depression.
  • The brain-gut axis health is closely related to depression, highlighting the importance of gut microbiome interventions.
