intended to present the fundamental biological principles of psychobiology/behavioral neuroscience to science undergraduate students. This course will cover the concepts of cellular and structural anatomy and physiology of the nervous system; the neurotransmitter systems and psychopharmacology; the functional anatomy of sensory systems‚ including vision‚ audition‚ olfaction‚ gustation and somatosensattion; and the motor system. Prerequisites: General Psychology (PSY1012) is a required prerequisite

He characterized messenger systems including IP3 receptors and inositol pyrophosphates. He identified novel neurotransmitters including nitric oxide‚ carbon monoxide and D-serine. Solomon H.

pathways with different functions. The drugs that block dopamine synapses produce their benefits by acting on neurons in the DA. This system is a set of neurons that project from the midbrain tegmentum to the limbic system (Kalat‚ 1998). This neurotransmitter system in the brain is where most drugs abuse their reinforcing effects that cause addiction (Phllips et al.‚ 2003). Control of this system‚ by the amygdala‚ can influence the incentive value of the sensory property of food and its modulation

Genetics‚ meaning that you inherit a genetic pre-disposition to depression or some other mental illness as someone in your close family had that mental illness‚ or down to neurotransmitter (serotonin‚ dopamine...) imbalances in your brain leading to mental illnesses such as depression (low serotonin levels). There is a large amount of evidence to back these assumptions up. Firstly in support of the theory that some mental illnesses

understanding of the functional anatomy of anxiety allows for a new perspective on the various anxiety disorders. The neurotransmitters involved in these circuits are reviewed for their relevance to the pharmacologic choices in the treatment of anxiety (i.e. Kang‚ Wilson & Wilson‚ 2000). Much research has been conducted on gamma-aminobutyric acid (GABA) as it is the major inhibitory neurotransmitter in the mammalian Central Nervous System (CNS) (i.e. Vekovischeva‚ Haapalinna & Sarviharju‚ 1999). GABA participates

These chemical messengers‚ called neurotransmitters‚ are released and received by the brain’s many nerve cells‚ which are also called neurons. Neurons are constantly communicating with each other by way of exchanging neurotransmitters. This communication system is essential to all of the brain’s functions. A tiny space called a synapse connects neurons to one another. Depression has been linked to problems or imbalances in the brain with regard to the neurotransmitters serotonin‚ norepinephrine‚ and

terminal neurotransmitters are stored ready to be released‚ across the synaptic gap‚ when the action potential arrives. The receptors on the post-synaptic neurone become occupied with the neurotransmitters resulting in a change in electrical charge. The neurotransmitters can either cause inhibition of the post-synaptic neurone‚ by suppressing the activity of the neurone and returning to the resting potential or excitation where by the activity of the neurone is increased. Each neurotransmitter resembles

Drugs and the nervous system Neurotransmitters within the body include excitatory and inhibitory‚ noradrenalin‚ dopamine‚ serotonin; acetylcholine and glutamate are examples of excitatory neurotransmitters. GABA and glycine are examples of inhibitory neurotransmitters. General anaesthetics General anaesthetics act mainly on the central nervous system to stop information processing; these may be given by inhalation or intravenously. Nitrous oxide or laughing gas is used in maintain anaesthesia
