Abstract

A derived response method of acquiring frequency specific auditory evoked potentials that utilizes a pure tone in combination with a toneburst is applied to the measurement of hearing sensitivity in guinea pigs, chinchillas and pocket gophers. Two experiments which demonstrate that thresholds acquired via tone-derived responses are 10 to 15 dB more sensitive than thresholds to solitary tonebursts are described. The derived potentials approximate behaviorally acquired thresholds at frequencies of 0.5 kHz and above. This technique may provide a more rapid means of assessing hearing sensitivity in laboratory animals than by behavioral means.

Classical conditioning after temporal lobe lesions in man: sparing of simple discrimination and extinction.

Recent reports of impaired conditional discrimination learning in temporal lobectomy subjects have raised the question of response inhibition deficits in these patients. In the present study, left and right temporal lobectomy subjects and healthy controls completed an eyelid conditioning task, which required simple two-tone discrimination learning, followed by extinction. There were no group differences with regard to discrimination learning or extinction. General deficits in response inhibition are therefore not likely to account for the impairment in conditional discrimination observed in temporal lobectomy patients.

Behavioral lifetime of human auditory sensory memory predicted by physiological measures.

Noninvasive magnetoencephalography makes it possible to identify the cortical area in the human brain whose activity reflects the decay of passive sensory storage of information about auditory stimuli (echoic memory). The lifetime for decay of the neuronal activation trace in primary auditory cortex was found to predict the psychophysically determined duration of memory for the loudness of a tone. Although memory for the loudness of a specific tone is lost, the remembered loudness decays toward the global mean of all of the loudnesses to which a subject is exposed in a series of trials.

Neuroethological evaluation of audiogenic seizures and audiogenic-like seizures induced by microinjection of bicuculline into the inferior colliculus. I. Effects of midcollicular knife cuts.

Audiogenic seizures (AS) are a model of generalized tonic-clonic seizures. The inferior colliculus (IC) and the GABAergic neurotransmission seems to be the most critical site and neurotransmitter system, respectively, of the auditory midbrain involved in AS origin and development. Thus, audiogenic-like seizures are evoked by GABAA antagonists such as bicuculline (BIC). Wistar audiogenic AS resistant (R) rats were sham-transected through the midcollicular line and microinjected with IC bicuculline (BIC; 80 ng/0.2 microliters) (n = 8); transected through the midcollicular line and microinjected with IC saline 0.9% (n = 8); transected through the cortex above the midcollicular line and microinjected with IC BIC (n = 3); transected through the midcollicular line up to 6.0 mm depth and microinjected with IC BIC (80 ng/0.2 microliters or 120 ng/0.3 microliters (n = 8). Wistar AS susceptible (S) rats were submitted to cortical transections (n = 8) and midcollicular transections (n = 7). Animals were studied by means of an ethological method before and after microinjections and/or transections in order to evaluate possible pathways in the AS-like evoked seizures. Bicuculline-evoked seizures were very similar to those evoked by acoustic stimulation, but lacked the tonic-clonic component. No modification in animal behavior was observed in the presence of sound, once the AS-like behavior was initiated. A small percentage of the animals, however, presented procursive behavior which was increased by sound. The IC BIC-evoked patterns were almost totally blocked by midcollicular but not cortical transections. Furthermore, midcollicular but not cortical transections blocked the tonic-clonic component of AS in genetically S animals without modifying the wild running component. These data suggest that the inferior colliculus-superior colliculus connection may be involved in the sensorimotor transduction necessary for AS-like behaviors.
