News There are many types of neurotransmitters in the brain—what they have in common is that they are produced inside a neuron, released into the synapse, and then cause an excitatory or inhibitory effect on receptor cells, helping to propagate or downgrade action potentials.here are many types of neurotransmitters in the brain—what they have in common is that they are produced inside a neuron, released into the synapse, and then cause an excitatory or inhibitory effect on receptor cells, helping to propagate or downgrade action potentials.

Serotonin Details. Serotonin, a chemical, is derived from the amino acid tryptophan. It is produced as necessary by the nervous system, mainly the brain, but also by special cells in the bronchial tubes (lungs) and gastrointestinal tract. In the blood, most serotonin, more than 90%, is found in the platelets.

Brain Electricity and the Mind Both utilize electricity in different ways. In fact, there are many different sources of electricity in the brain. If consciousness in nature, and the human brain, is in the form of information, electromagnetic or otherwise, it is not clear yet how this could work. Where does brain electricity come from and what does it mean? Measuring Electricity in the Brain Current methods of measuring electricity in the brain utilize probes either on the scalp (the least intrusive method), below the skull coverings such as the Dura at the edge of the brain, and deep inside the brain.

Big Stick Diplomacy Was a term used to coin Theodore Roosevelt's Monroe doctrine-like policy. It falls under the theory to try to negotiate carefully, and if not, wave a big stick (the military) at the country of contention. Was a term used to coin Theodore Roosevelt's Monroe doctrine-like policy. It falls under the theory to try to negotiate carefully, and if not, wave a big stick (the military) at the country of contention. In short, his Diplomatic policy focused on aggressive but peaceful control while obtaining the objectives he wants.

Which brain chemicals cause which emotions? · just now. Report Abuse. Emotions aren't caused by one specific chemical in the brain. There are a number of neurotransmitters, or chemicals in the brain that perform different functions and carry impulses from one part of the brain to the other.Some of these include serotonin, dopamine, acetylcholine, epinephrine, norepinephrine, GABA, etc.hese parts of the brain are the hardware, the chemicals that they use as communicators may be considered as being our software. Emotions are neuropeptides attaching to receptors and stimulating an electrical change on neurons.

Overview Cerebrospinal fluid is produced by tissues lining the ventricles of the brain. It flows through the ventricles by way of interconnecting channels and eventually flows into spaces around the brain and spinal column. It's absorbed primarily by blood vessels in tissues near the base of the brain.

blood-brain barrier Lipid-soluble substances such as alcohol, caffeine, nicotine and most anaesthetics, as well as glucose, oxygen and water, pass rapidly into brain cells, whereas proteins, most antibiotics and ions do not enter or enter very slowly. The mechanism protects brain cells against harmful substances and pathogens.

What is the brain made of and? The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem.

Schizophrenia Chemistry. Genetics help to determine how the brain uses certain chemicals. People with schizophrenia have a chemical imbalance of brain chemicals (serotonin and dopamine) which are neurotransmitters. These neurotransmitters allow nerve cells in the brain to send messages to each other.

Histamine And The Nervous System Histamine is synthesised in the brain in the hypothalamus, in a specific area known as the tuberomamillary nucleus (TMN), where it acts as a signalling messenger (or neurotransmitter). The hypothalamus is the area of the brain that overseas the metabolic processes of the body found in the central nervous system.

temporal arteritis Temporal arteritis is also called giant cell arteritis or cranial arteritis. It is a rheumatic disease that affects large and medium-sized arteries throughout the body and can occur in a variety of patients. Although the temporal arteries are most commonly affected, other arteries throughout the body may be affected.he term temporal arteritis literally means inflammation of the temporal arteries.. As implied by the name, these blood vessels run along the temples after they branch off from the carotid artery in the neck.

Brain Chemistry (Neurochemistry) So are emotions, such as sadness, grief, and stress. When the brain tells the body to do something, such as to sit down or run, this also sets a chemical process in motion. These chemical communicators, or neurotransmitters, are the words that make up the language of the brain and the entire nervous system.The billions of tiny neurons in the brain communicate with each other across small spaces called synapses (SIN-ap-siz).he chemical may be pumped back into the nerve ending it comes from, a process known as reuptake, it may be destroyed by enzymes * near the receptor sites, or it may simply spread out into the surrounding area of the brain and be destroyed there.
