Chapter 1: Biospyschology as a Neuroscience Flashcards
What is a neuron?
Cells that receive and transmit electrochemical signals that create the human brain.
How many neurons and connections are in the brain?
90 billion neurons with 100 trillion connections among them, and an infinite number of paths that neural signals can follow.
What is Neuroscience?
The scientific study of the nervous system comprising of many disciples.
What is Biopsychology?
The scientific study of the biology of behaviour. Also known as psychobiology, behavioural biology, or behavioural neuroscience.
What is Neuroanatomy?
Looks.
Structure of the nervous system.
What is Neurochemistry?
Chemical bases of neural activity.
What is Neuroendocrinology?
Transmissions.
The interactions between the nervous system and the endocrine system.
What is the endocrine system?
Glans and organs that make hormones.
Endocrine glands secrete hormones straight into the bloodstream. Hormones help to control many body functions, such as growth, repair and reproduction.
What is Neuropathology?
Damage.
Nervous system dysfunction.
What is Neuropharmacology?
Chemical reaction.
Effects of drugs on neural activity.
What is Neurophysiology?
Functions and activities of the nervous system.
What are the main difference between human and animal brains?
Overall size and the extent of their cortical (higher functioning) development.
Otherwise similar in fundamental ways.
Between-subjects design
Different group of subjects is tested under each condition.
Within-subjects design
Test the same group of subjects under each condition.
Independent variable
Difference between the conditions being compared.
Dependent variable
Effect caused by the independent variable.
Confounded variable
Variable the influences both in-and dependent variable.
What is the Coolidge effect and its relevance to confounding variables?
Animal male exhibit renewed sexual interest whenever a new female is introduced, even after sex with prior but still available sexual partners.
Fatigue in males was discovered as a confounding variable. Controlled by using 2 males both fatigued for a female to decide (went for new male).
What are Quasiexperimental studies and why are they used?
Studies of groups of subjects who have been exposed to the conditions of interests in the real world.
Used due to physical or ethical impediments.
The statement ‘frequent alcohol use is associated with brain damage’ is likely a conclusion from what study?
Quasiexperimetal studies as they can only correlate with each other.
Note: language ‘associate’ rather than ‘causes’.
What are Case studies and its major problem?
Focus on a single subject, or a very small number of subjects.
Generalisability. Degree to which results can be applied to other cases.
Difference between pure and applied research?
Pure is motivated by the curiosity of the researcher, whereas applied is intended to bring benefit to humankind.
What is translational research?
Aims to translate pure findings into useful applications for humankind.
What is Physiological psychology and an example from memory research?
Study of neural mechanisms of behaviour by manipulating the nervous systems of nonhuman animals in controlled experiments.
E.g. surgically removing a rats hippocampus and assessing their ability to perform various memory tasks.
