Earthworms have photoreceptor cells to detect light and darkness. These cells help them navigate their environment and determine whether it is day or night. This information is crucial for their survival, as it helps them find food, avoid predators, and regulate their behavior and activity patterns.
agonists Chemical substances that mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell, increasing or decreasing the activity of that cell. Drug that enhances the effects of a particular neurotransmitter.
Yes, exogenous neurotransmitters are chemicals that are taken from outside the body and can affect neurotransmitter activity in the brain. These can include medications like antidepressants and stimulants that alter the levels of neurotransmitters like serotonin, dopamine, and norepinephrine.
Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. It works to reduce the activity of neurons, thus promoting relaxation and reducing anxiety. Dysregulation of GABA signaling has been linked to various neurological conditions, such as epilepsy and anxiety disorders.
Acetylcholine functions as both a neurotransmitter in the nervous system, where it is involved in transmitting signals between nerve cells, and as a neuromodulator that influences the activity of other neurotransmitter systems. It plays a critical role in muscle contraction and movement, as well as in memory, learning, and attention.

The binding of a neurotransmitter to a dendrite will cause one these three things to happen:excitement (stimulation)inhibition (stop activity)modulation (change activity by slowing it or increasing it)It all depends on the neurotransmitter. Neurotransmitter are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.

The parietal lobe primarily uses neurotransmitters such as glutamate and GABA. Glutamate is excitatory and involved in processing sensory information, while GABA is inhibitory and helps regulate the activity of glutamate to maintain a balance in neural signaling within the parietal lobe.

The interaction between benzodiazepines (benzos) and dopamine can disrupt the brain's neurotransmitter balance. Benzos can enhance the effects of dopamine in certain areas of the brain, leading to an imbalance in neurotransmitter activity. This can result in changes in mood, behavior, and cognition.
