Excitatory and Inhibitory Effects of Neurotransmitters

Excitatory and Inhibitory Effects of Neurotransmitters

When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...

Diencephalon: Thalamus and Information Relay

Diencephalon: Thalamus and Information Relay

The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological states or needs.

Adrenergic Neurons: Neurotransmission

Adrenergic Neurons: Neurotransmission

Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.
Synthesis: Catecholamine synthesis requires tyrosine, which is taken...

Area of Science:

Neuroscience
Neurobiology

Background:

The nucleus accumbens is a key brain region for reward and motivation.
Understanding how different brain areas communicate with the nucleus accumbens is crucial for deciphering its function.

Discussion:

This study used optogenetics to selectively activate glutamatergic inputs from the amygdala, prefrontal cortex, and hippocampus into the nucleus accumbens.
The researchers examined the functional consequences of activating each pathway in both living animals (in vivo) and brain slices (ex vivo).

Key Insights:

Distinct glutamatergic pathways from the amygdala, prefrontal cortex, and hippocampus differentially influence nucleus accumbens activity.
This provides a more detailed map of information flow into the nucleus accumbens.

Outlook:

Further research can explore how these pathways interact and contribute to complex behaviors.
This work lays the foundation for understanding neurological disorders involving the nucleus accumbens.
