The Effect Of Para-Chlorophenylalanine And Scopolamine On Passive Avoidance In Chicks, Bruce A. Mattingly, James F. Zolman
The Effect Of Para-Chlorophenylalanine And Scopolamine On Passive Avoidance In Chicks, Bruce A. Mattingly, James F. Zolman
Faculty Research at Morehead State University
Four-day-old Vantress x Arbor Acre chicks were tested for key-peck passive avoidance (PA) learning following intraperitoneal injections of parachlorophenylalanine (PCPA) and/or scopolamine. In Experiment 1, chicks were pre-treated with either three or five injections of PCPA (150 mg/kg) or saline across the first three posthatch days and then tested for PA learning on the fourth posthatch day. In Experiment 2, chicks were first pre-treated with three injections of PCPA (150 mg/kg) or saline, and then injected with either scopolamine (0.5 mg/kg) or saline 20 rain prior to PA testing on the fourth posthatch day. Major findings were: (a) Chicks pre-treated …
Atropine Disrupts Passive Avoidance Learning In Young Chicks T, Bruce A. Mattingly, James F. Zolman
Atropine Disrupts Passive Avoidance Learning In Young Chicks T, Bruce A. Mattingly, James F. Zolman
Faculty Research at Morehead State University
Four-day-old Vantress × Arbor Acre chicks were first trained to key-peck for heat reinforcement and then tested for passive avoidance learning following an intraperitoneal injection of atropine sulfate or saline. Chicks injected with 1.0 mg/kg of atropine responded more quickly than saline-injected chicks when their key-peck responses were punished with aversive wing-shocks. These findings, therefore, are consistent with the view that cholinergic mechanisms are involved in inhibitory behavior in the young domestic chick.
Death Education In U.S. Medical Schools: 1975-1980, George E. Dickinson
Death Education In U.S. Medical Schools: 1975-1980, George E. Dickinson
Faculty Research at Morehead State University
Surveys from 1975 and 1980 of U.S. medical schools' offerings in death education are compared. A 95 and 96 percent return rate, respectively, for each survey revealed a slight increase in offerings in 1980. A team approach is used, with physicians and theologians most often being cited as facilitators of a lecture/ discussion format.
The Impact Of Federal Regulations On The Small Coal Mine In Appalachia, Bernard Davis
The Impact Of Federal Regulations On The Small Coal Mine In Appalachia, Bernard Davis
Faculty Research at Morehead State University
The study addresses two specific issues influencing the production of coal from small mines: 1) the direct costs and other effects of government regulation and deregulation on coal operators in general, and 2) the effects of governmental policies on the productivity by size (tonnage) class of small coal mines. Appalachian Kentucky was used as the study area because of the wide range of mine firm sizes.
The Lchthyofauna Of The Big Sandy River Basin, With Special Emphasis On The Levisa Fork Drainage, Jerry F. Howell Jr.
The Lchthyofauna Of The Big Sandy River Basin, With Special Emphasis On The Levisa Fork Drainage, Jerry F. Howell Jr.
Faculty Research at Morehead State University
A literature and regional repository review of the Big Sandy Basin ichthyofouno yielded 111 confirmed species, including 93 from Leviso Fork and its tributaries. Twenty-nine additional species were added to the lost published comprehensive review (Jenkins et al., 1972); one species was not re-confirmed. The 111 forms (108 confirmed or probable) included 14 known or suspected introductions and 20 species (including 12 recently collected from Leviso Fork) with special Kentucky Nature Preserves Commission status codes. The two most threatened Kentucky species were Percino macrocephala and Ammocrypto pellucido.
