The brain is split into the left and right hemispheres. Different brain areas are divided by deep grooves called sulci.There are nine parts of the human brain. These nine parts are the Broca’s area‚ Cerebellum‚ Cerebrum‚ Frontal lobe‚ Motor area‚ Occipital lobe‚ Parietal lobe‚ sensory area‚ and temporal lobe. The brain is split into the left and right hemispheres. Different brain areas are divided by deep grooves called Sulci. There are five key parts of the brain that controls the function of your

Being happy was not part of his emotion‚ being abused‚ shifted to an orphanage and losing his father at an early age condensed any feeling of happiness in his life.

has to pass through the stomach first. Once in the brain drugs affect chemicals called neurotransmitters. These are the chemicals that control the flow of information within the brain between the neurons or brain cells‚ forming a synapse. Neurotransmitters also alter people’s moods and feelings. Different drugs can affect different neurotransmitters. For example‚ ecstasy appears to affect a neurotransmitter called serotonin by reducing the amount of the chemical in the brain. Those people with lower

1 EFFECTS OF ALCOHOL ON BRAIN FUNCTIONING & NEUROTRANSMITTERS When alcohol is consumed the brain is unable to send the correct messages through the body and disrupts communication between the nerve cells . It suppresses nerve activity‚ throughout the cerebral cortex and the central nervous system (CNS) by significantly slowing down the pace of actions taken and information received . Consumption also alters two of the major neurotransmitters within the brain being the Hippocampus and the Prefrontal

Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine‚ the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through

advances‚ there is a strong push to find the safest and most effective ways to relieve pain. The most understood pain-relieving system in the body is the endogenous opioid system. The endogenous opioid system produces three opioids‚ which act as neurotransmitters to mediate and inhibit the transmission of pain stimulus (Holden‚ Jeong‚ and Forrest 2005). Opiate drugs act on receptors of the endogenous opioid systems

drug rapidly into the bloodstream and brain‚ producing a quicker and stronger but shorter-lasting high than snorting. Cocaine interferes with the neurotransmitters in the brains causing them to increase the production level of dopamine‚ the feel good chemical of the brain. Not only does the cocaine produce more dopamine it also stops the neurotransmitters from reabsorbing and recycling the dopamine. This means that the dopamine begins to build up causing the users high. The pile up of dopamine causes

Evaluation of Evolutionary Theory of Altruism And The Role Of Genes-A Modern View Background: Evolutionary theory holds that organisms with the strongest genes for survival and reproduction do‚ in fact‚ survive and reproduce most successfully. They thus multiply their genes most widely‚ spreading the advantageous genes through whole populations. Ceaseless repetitions of the process can gradually transform species into totally new ones. Such a world seems to have no place for self-sacrificing

insufficient neurotransmitters such as serotonin and nor-adrenaline. They will either reduce the amount of re-absorption or block the enzyme that is trying to break down neurotransmitters. Allowing to increase the amount of neurotransmitter available ‚ so that neighbouring cells become excited. Tricyclics are used to block the transporter mechanism that re-absorbs both serotonin and nor-adrenaline into the pre-synaptic cell after it has fired. As a result to this there are more neurotransmitters left
