Depression of Neuronal Function: Alcohol acts as a general depressant of the central nervous system. It inhibits the function of neurons by reducing their ability to transmit electrical impulses. These impulses carry essential information for normal brain function. Essentially, alcohol dampens neuronal communication1.

Interaction with Receptors:

GABA Receptors: Alcohol can bind to GABA receptors, holding the ion channels open longer. This increases the entry of chloride ions (negative charges) into neurons.

Glutamate Receptors: Alcohol also binds to glutamate receptors, decreasing the entry of sodium and calcium (positive charges) into neurons2.

Endocannabinoid System: Alcohol exposure affects the endocannabinoid (eCB) system, which plays a role in synaptic function. Brain region-specific effects include altering the synthesis of endocannabinoids (such as anandamide and 2-AG), their precursors, and the density and coupling efficacy of CB1 receptors. These alterations impact synaptic function, including neuronal excitability and postsynaptic conductance3.

In summary, alcohol disrupts synaptic communication, affecting neurotransmitter release and receptor activity. The overall inhibitory effect on the brain resembles that produced by other sedative drugs. If you have more questions or need further details, feel free to ask! 😊
