Neurokeemias

Neurokeemias is a term that refers to the chemical substances involved in neural communication. These chemicals, primarily neurotransmitters and neuromodulators, are essential for the proper functioning of the nervous system. Neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, triggering a response. Examples include acetylcholine, dopamine, serotonin, and GABA. Neuromodulators, on the other hand, are released in smaller quantities and can affect a larger area of neurons, altering their sensitivity to neurotransmitters.

The intricate interplay of neurokeemias is fundamental to a vast array of brain functions, including mood regulation, learning and memory, motor control, and sensory perception. Imbalances or dysregulation in these chemical systems are implicated in various neurological and psychiatric disorders. For instance, altered levels of dopamine are associated with Parkinson's disease and schizophrenia, while serotonin imbalances are linked to depression and anxiety. Research into neurokeemias is ongoing, aiming to understand their precise roles and to develop targeted therapeutic interventions for conditions affecting the brain.
