Orexin has a key function in human neurology and physiology. It is a regulator in and around the hypothalamus which affects one's hunger, fatigue and general arousal. Though its quantity in our anatomy is far less than that of of other neurotransmitters, its role is no less important.
What else can I help you with?
Works by increasing activity in certain areas of the brain to increase concentration and wakefulness?
Orexin increases activity in certain areas of the brain to increase concentration and wakefulness. Orexin reacts with norepinephrine neuron receptors.

Why would a lack of neurotransmitter change the function of the brain?
Yes, signals would not pass between the nerve cells.
How do the nerves get to the brain?
neurotransmitter!!!
How does the brain's ability to adapt when it experiences long periods of too much or too little neurotransmitter help it maintain homeostasis?
The brain can adapt to long periods of too much or too little neurotransmitter by adjusting the sensitivity of its receptors or by changing the production of neurotransmitters. This helps maintain homeostasis by ensuring that communication between neurons remains balanced. Over time, the brain can make structural changes to optimize its function despite fluctuations in neurotransmitter levels.
What affects do inhalants have on the brain?
Inhalants can lead to a range of effects on the brain, including damage to brain cells, neurotransmitter imbalances, and decreased cognitive function. Prolonged use can result in permanent brain damage and cognitive impairments.
Could intelligence be primarily a matter of having plenty of the right neurotransmitter at the right synapses?
Optimal neurotransmitter function certainly would help a brain reach its full intellectual potential. However, neuronal connections are what hold the data of intelligence in the first place. However optimal neurotransmitter function encourages the new neuronal connections.
How does the accumulation of adenosine in the brain affect cognitive function and overall brain health?
The accumulation of adenosine in the brain can lead to decreased cognitive function and impact overall brain health. Adenosine is a neurotransmitter that can inhibit brain activity, causing drowsiness and impairing cognitive processes such as memory and decision-making. This can result in reduced mental clarity and alertness, affecting overall brain function.
What is the study of how alcoholism affects the brain function of an individual?
The study of how alcoholism affects the brain function of an individual is known as alcohol neuroscience or alcohol-related neurobiology. It involves researching the impact of chronic alcohol consumption on brain structure, function, and neurotransmitter systems, as well as understanding the cognitive and behavioral consequences of alcoholism.
Is dopamine an Inhibitory transmitter?
No, dopamine is not an inhibitory neurotransmitter. It is a type of monoamine neurotransmitter that acts as both an excitatory and modulatory neurotransmitter in the brain.
How does alcohol alter brain function?
Alcohol alters brain function by affecting neurotransmitter levels, disrupting communication between brain cells. It particularly affects the inhibitory neurotransmitter GABA, leading to decreased inhibition and increased dopamine release, resulting in the characteristic effects of alcohol intoxication. Over time, chronic alcohol use can lead to changes in brain structure and function, impacting memory, decision-making, and emotional regulation.
What is the most common excitatory neurotransmitter in the brain?
Glutamate
