The de novo protein synthesis theory of memory formation is a hypothesis about the formation of the physical correlates of memory in the brain.It is widely accepted that the physiological correlates for memories are stored at the synapse between various neurons.
This bidirectional communication between astrocytes and neurons add complexity to brain signaling, with implications for brain function and neurological disorders. [10] [11] Enzyme degradation – proteins called enzymes break the neurotransmitters down. Reuptake – neurotransmitters are reabsorbed into the pre-synaptic neuron.
Neuropeptide Y has been indicated as playing an important role in neurogenesis in various parts of the brain. Two particular brain areas where NPY affects neurogenesis are the sub-ventricular zone and the dentate gyrus of the hippocampus. These areas are where cell growth and proliferation occur into adulthood. [16]
The glutamate/GABA–glutamine cycle is a metabolic pathway that describes the release of either glutamate or GABA from neurons which is then taken up into astrocytes (non-neuronal glial cells). In return, astrocytes release glutamine to be taken up into neurons for use as a precursor to the synthesis of either glutamate or GABA. [2]
Neurons form complex biological neural networks through which nerve impulses (action potentials) travel. Neurons do not touch each other (except in the case of an electrical synapse through a gap junction); instead, neurons interact at close contact points called synapses. A neuron transports its information by way of an action potential.
It is an enzyme that catalyzes the breakdown of acetylcholine and some other choline esters that function as neurotransmitters: acetylcholine + H 2 O = choline + acetate. It is found at mainly neuromuscular junctions and in chemical synapses of the cholinergic type, where its activity serves to terminate cholinergic synaptic transmission.
Epinephrine is produced in small groups of neurons in the human brain which express its synthesizing enzyme, phenylethanolamine N-methyltransferase; [8] these neurons project from a nucleus that is adjacent (ventrolateral) to the area postrema and from a nucleus in the dorsal region of the solitary tract.
Acetylcholine is a choline molecule that has been acetylated at the oxygen atom. Because of the charged ammonium group, acetylcholine does not penetrate lipid membranes. . Because of this, when the molecule is introduced externally, it remains in the extracellular space and at present it is considered that the molecule does not pass through the blood–brain
