Neurological Basis of Psychology Psychology Program Faculty 01 Objectives: At the end of this lesson, the students will be able to: 1. Explain the role of neurons in human behavior. 2. Discuss the parts and functions of the neuron. 3. Discuss the parts and functions of the nervous system and their role in controlling human behavior. 4. Identify the different parts of the brain and their corresponding functions. 5. Ascertain the parts and functions of endocrine glands especially its role in influencing behavior. 02 NEUROLOGICAL BASIS OF PSYCHOLOGY 12 BILLION OR BASIC BUILDING MORE BLOCKS THE INFORMATION- PROCESSING UNITS RECEIVING AND TRANSMITTING NEURON TRANSMITTING MESSAGES 03 PARTS OF THE NEURON 04  PARTS OF NEURON AND ITS FUNCTIONS DENDRITES SOMA (CELL BODY) AXON MYELIN SHEATH The root like part Contains the nucleus Wire-like structure A fatty layer of tissue of the cell that (brain) of the cell.

Social Science Class 06  Neurotransmitters Chemical messengers that transmit electrical impusles between neurons within 1/10,000th of a second. Synaptic Gap The gap between two neurons. Through this gap, information is passed by the neurotransmitter from the sending neuron to the receiving neuron. 07 Youtube Video: https://www.youtube.com/watch?v=mItV4rC57kM  Major Neurotransmitters It helps the neurons recover after GABA transmission (GAMMA AMINO BUTYRIC ACID) Reduces anxiety and stress It is a significant mood modulator It is one of the most common contributors to mood problems. SEROTONIN It is the key to our feelings of happiness and very important to our emotions 11  It is also known as "adrenaline" and is a neurotransmitter and hormone essential to EPINEPHRINE metabolism It regulates attention, mental focus, arousal and cognition. Responsible for motivation, interest, and drive. DOPAMINE It is associated with positive stress states such as being in love, exercising, listening to music, and sex. It is the major excitatory neurotransmitter in the brain. It is required for learning and GLUTAMATE memory. Low levels can lead to tiredness and poor brain activity. 12  It helps control the sleep-wake cycle. HISTAMINE It promotes the release of epinephrine and norepinephrine Also known as noradrenaline that is produced by the adrenal medulla or mode NOREPINEPHRINE from dopamine. High levels are linked to anxiety, stress, high blood pressure, and hyperactivity Important in focus and concentration High levels experience "mind racing", sleep PEA problems, anxiety and schizophrenia (PHENETHYLAMINE) Low levels experience difficulty paying attention or thinking clearly, and depression. 13
