foundation of Psychology involves the electrical and chemical processes in the nervous system that cause us to feel‚ have fears‚ and develop thoughts. There are many biological factors that can influence psychological functioning. From the neuron to the different parts of the nervous system‚ each can impact mental processes and behavior. Genetics and evolution can also influence psychological functioning. Genetics and evolution interact in ways that psychologists are still trying to understand

For the purpose of this assignment I will be looking at this question in two parts. Firstly I will explain how neurons transmit information in the human body and secondly I will discuss how knowing how neurons function within our bodies helps us understand different aspects of human behaviour. I will be using information gathered from Book 1 (Mapping Psychology). External and internal factors and conditions are detected by the body’s nervous system. These changes are detected‚ interpreted and

basic functioning units of the nervous system are nerve cells‚ or neurons. Neurons are specialized cells of the nervous system that transmit signals throughout the body. The most important structures of a neuron are the long extensions that extend out from the cell body which are Dendrites and Axons. Dendrites are extensions of neurons that receive signals and conduct them toward the cell body whereas Axons are extensions of neurons that conduct signals away from the cell body to other cells. When

System The nervous system is made up of neurons. Neurons communicate just like people do‚ but they send messages using action potentials (electricity passing through their axons). Each neuron picks up signals at its dendrites‚ passes the signals down the axon‚ into the axon terminals‚ and into the synapses. The synapse then drops neurotransmitter into the synaptic cleft between the first neuron’s synapse and the next neuron’s dendrites. That signals neuron #2 to pass the message on. 2.2.b What

___________________________‚ which brings the membrane potential closer to the point at which the action potential will occur. If (12) ___________________ (the voltage at which an action potential is generated) is reached at the (13) ______________ ________ (area) of the neuron‚ then an action potential will be generated because (14) ________________________-gated (15) ________________ (ion) channels will open. The – (16) efflux / influx (circle or highlight one) – of these ions will cause more channels to open‚ moving the

Neurons communicate with each other by sending electrical signals‚ nerve impulses‚ through tube like structures called axons.

A baby’s brain is like a lantern; it is vaguely aware of everything. Children have more neurons actively working than adults because the brain provides too many connections before it decides which ones to keep. This means that children are overly sensitive to stimuli in their environment. Children will absorb information from any environment that they are placed in: school‚ home‚ or on the streets. If a child is exposed to negative stimuli‚ the risk of future psychological defects is increased exponentially
