act on the neurotransmitters responsible for carrying the vestibular signal from primary vestibular neurons. That is‚ these drugs seek to block the conduction of impulses from the semicircular canals and otolith organs‚ before these nerve impulses reach central vestibular structures (Smith & Darlington‚ 1996). The vestibulo-ocular reflex is a reflex eye movement‚ which is imperative in the control of balance. It functions to stabilize images on the retinas. Six primary neurotransmitters have been

M1 Nature is the genetic and biological influences on an individual and their development; it is based on genes and what is inherited from them. Nurture is the social‚ economic and environmental influences on an individual and their development; it based on personality and how behaviour is learnt. Determinism is the belief that you future is fixed and influenced purely naturally by what is genetically inherited or that your future is unpredictable and can change over time depending on choices made

The healthiness of coffee has been a topic of debate for many years. Being one of the most common drinks in the world‚ people have argued all sorts of positions in regards to its benefits or detriments to their health. Kris Gunnars’ article‚ “13 Health Benefits of Coffee‚ Based on Science” argues that coffee is indeed healthy‚ and provides thirteen reasons why. Jim Dillan’s article‚ “7 Negative Effects of Coffee & The Healthy Drink You Should Replace it With‚” argues the opposite‚ claiming that coffee

Further extraneuronal locations include among others lymphocytes‚ monocytes‚ and foetal tissue. 5-HT3 receptors modulate the release of neurotransmitters and neuropeptides like dopamine‚ cholecystokinin‚ acetylcholine‚ GABA‚ substance P‚ and serotonin itself. They have been demonstrated to be involved in sensory transmission‚ regulation of autonomic functions‚ integration of the vomiting reflex

In the essay “seeking the roots on violence” Anastasia Toufexis stated that “for one thing‚ genes help control production of behavior relating chemicals. One suspect substance is the neurotransmitter serotonin.” Someone that has a chemical imbalance in the brain can cause depression and violence. Serotonin is chemical in our brain that controls ones mood. When a person is clinically classified as depressed he or she is prescribed to

will cause Na+ to rush into the axon‚ triggering an action potential. Once that happens then the action potential will propagate down the axon until it reaches the terminal button. Here‚ Ca++ will enter the cell. This stimulates exocytosis of neurotransmitter molecules (acetylcholine in this case). We have that then the acetylcholine will travel across the synaptic cleft and bind on receptors located on the motor end plate. The motor end plate is a specialized plasma membrane found in muscle cells

because most of the recreational substances we indulge in‚ work on exactly the same brain bits that love does. It all comes down to what love does to a couple of chemicals in your brain: dopamine and noradrenaline. Dopamine and noradrenaline are neurotransmitters - they get released from nerve cells‚ switch on other nerve cells that are sensitive to them‚ and then get reabsorbed. (Complicate that by a factor of about 40 zillion and you’re somewhere near the reality of how the brain works‚ because by switching
