Hypertropia is a condition of misalignment of the eyes ( strabismus ), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated vertical deviation is a special type of hypertropia leading to slow ...
Actogram. An actogram is a plot that shows rhythms in biological variables throughout the day. Traditionally, actograms describe phases of activity and rest, but they have also been used to visualize rhythms in protein phosphorylation, gene expression, and hormone secretion.
Vacuum activities (or vacuum behaviours) are innate fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus ( releaser) that normally elicit them. [1] This type of abnormal behaviour shows that a key stimulus is not always needed to produce an activity. [2] Vacuum activities often take place when an ...
Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments. [ 1][page needed] This field of psychology takes an empirical and practical approach when ...
In experimental psychology, a stimulus is the event or object to which a response is measured. Thus, not everything that is presented to participants qualifies as stimulus. For example, a cross mark at the center of a screen is not said to be a stimulus, because it merely serves to center participants' gaze on the screen.
Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [ 1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [ 2] In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal ...
The following outline is provided as an overview of and topical guide to neuroscience: Neuroscience is the scientific study of the structure and function of the nervous system. [1] [2] It encompasses the branch of biology [3] that deals with the anatomy, biochemistry, molecular biology, and physiology of neurons and neural circuits.
Biorhythm (pseudoscience) The biorhythm theory is the pseudoscientific idea that peoples' daily lives are significantly affected by rhythmic cycles with periods of exactly 23, 28 and 33 days, [ 1][ 2][ 3] typically a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle. The idea was developed by Wilhelm Fliess in the ...
