What is psychology? The scientific study of behaviour and the physiological and mental processes that underlie such behaviour. A profession that applies the findings of psychological research to real world problems Wilhelm Wundt First psychology lab in 1879 Main focus was on consciousness Many students established research labs in North America and Germany.

Running Head: Biological Psychology Paper Biological Psychology Paper Biological Psychology Paper Biological psychology is a vital part of psychology; without it psychology would not be considered a science‚ rather it may still be considered an art. Biological psychology has an extensive history‚ and each step has brought us closer to the reality that the brain is our main power source‚ and how much it affects our behavior. There have been many scientists and theorists that have contributed

different parts. The video describes the three important jobs our neurons do: receive information from other cells‚ process information‚ and transmit it to the rest of the body. Without our neurons we would have no brain activity. All behavior begins with an action from a neuron. First the brain gathers information from the receptors and spread it around it’s branch fibers‚ or dendrites. Next the information is sent to the soma‚ the neurons cell body‚ where it is combined with other information. Finally

break between the nerve and muscle to activate contraction. The progression in which signals are sent from motor neurons to skeletal muscle fibres to warrant movement of muscles is called neuromuscular junction (Etherington & Hong‚ 2011). Motor neurons‚ Schwann cells‚ muscle fibres and kranocytes are all the different cell types that make up the neuromuscular junction. Motor neurons send out axons to skeletal muscles where an action potential is passed along the axons. The axons form a synaptic

This disease affects a person’s motor neurons affecting voluntary motor control by damaging both the upper motor neuron and lower motor neuron. 2. Which patient findings/observations lead you to your primary diagnosis? How do they relate to the primary diagnosis? (1 point) It was Harry’s general weakness his clumsiness‚ and his suffering

can lose touch with reality‚ a key symptom of schizophrenia. Further support that mental illness is caused by structural defects is a tissue samples of brain neurons taken from mono-zygotic twins in which one is normal and the other effected. In the affected twin their neurons are disorganized‚ compared with the unaffected twin whose neurons are organized. This supports the theory that mental illness is caused by structural abnormalities as the normal twin has a different brain structure to that

damages dopamine neurons. Research shows that it is “the most addictive” drug in the world. Regardless of how the drug is utilised‚ it ultimately enters the bloodstream and through its lipophilic nature can cross the blood-brain-barrier (Figure 3) to reach the brain. Methamphetamine alters the release or “reuptake” of neurotransmitters in the brain‚ the most affected of which is dopamine‚ a chemical that assists in transmitting signals and is produced by the dopaminergic neurons located in the midbrain

Inhibitory transmitters free by interneurons within the spinal cord; 4. Inhibitory transmitters free from supraspinal sources. The concept of a single neuron discharging a single transmitter within the synaptic cleft clearly doesn’t relate to the dorsal horn. While exocytotic relief of separate peptide or amino
