(18) Tyrosine hydroxylase (TH) and phenylethanolamine-N-methyltransferase (PNMT) activities were assayed in adrenal glands of the following groups of the Alaskan red-backed vole (Clethrionomys rutilus dawsoni): 1) laboratory reared at 20 degrees C and 2) exposed to 5 degrees C for 1, 3, 7, and 28 days; 3) wild, summer acclimatized; 4) wild, fall acclimatized; and 5) wild, winter acclimatized.
(19) Acclimatized rats showed an increased activity of mitochondrial glutamate dehydrogenase without changes in glycolytic enzyme activity in skeletal muscle, heart and liver.
(20) Glucose also lowered the steady potential, whatever the previous acclimatization temperature, when the external sodium concentration was low.4.
Habituation
Definition:
(n.) The act of habituating, or accustoming; the state of being habituated.
Example Sentences:
(1) Effects of habitual variations in napping on psychomotor performance, short-term memory and subjective states were investigated.
(2) Based on our results, we propose the following hypotheses for the neurochemical mechanisms of motion sickness: (1) the histaminergic neuron system is involved in the signs and symptoms of motion sickness, including vomiting; (2) the acetylcholinergic neuron system is involved in the processes of habituation to motion sickness, including neural store mechanisms; and (3) the catecholaminergic neuron system in the brain stem is not related to the development of motion sickness.
(3) II, the visual and auditory stimuli were exposed conversely over the habituation- (either stimulus) and the test-periods (both stimuli).
(4) The hypothesis that the standard acoustic startle habituation paradigm contains the elements of Pavlovian fear conditioning was tested.
(5) From the third day to the fourth week after this treatment, there was some recovery of the SF rate, and the SCR tended to reappear with a marked slowing down of its habituation.
(6) Regardless of the habitual diet, a test meal accentuated the rate of triacylglycerol appearance in whole plasma and in the very low density lipoproteins of Triton WR-1339-treated monkeys, and the rate of increase of the protein component after feeding was slightly higher.
(7) This contrasts sharply with the reduction in both the frequency and surface area of sensory neuron active zones that accompanies long-term habituation, and suggests that modulation of active zone number and size may be an anatomical correlate that lies in the long-term domain.
(8) Infants were habituated to models posing either prototypically positive displays (e.g., happy expressions) or positive expression blends (e.g., mock surprise).
