Description
An account of the resource
A major finding in the visual plasticity literature is that visual deprivation is effective only during an early 'sensitive' period, which is lengthened by dark rearing. Unresolved is whether the visual cortex is in a normally plastic state prior to light stimulation. This cannot be addressed using paradigms employing light exposure to assess plasticity. Several developmental studies have investigated a plastic phenomenon termed long-term potentiation (LTP) in slices from cat (J. Neurophysiol., 59 (1988) 124-141) and rat (Brain Res., 439 (1988) 222-229) visual cortex. Susceptibility to the induction of LTP parallels the period of sensitivity to visual deprivation. This suggests that slices can be used to assay visual cortical plasticity, avoiding light exposure. In the present study, field potentials were recorded from slices of the primary visual cortices of dark-reared (DR) and control (CONT) Long Evans hooded rats (17 to 21 days). Field potential profiles recorded before and 90 min following tetanic electrical stimulation were subjected to current source density analysis, yielding extracellular current sink amplitudes. Tetanus resulted in LTP in both CONT and DR slices, but DR slices were significantly less potentiated. These results indicate that the primary visual cortex of DR animals is not fully plastic, indicating a role for light stimulation in inducing visual cortical plasticity.

Description
An account of the resource
Due to the curved path they follow, the visual callosal projections to areas OC1 and OC2 of the rat visual cortex have been inaccessible to studies using brain slices. In this paper we describe a new slice preparation in which a curved cutting blade was used to obtain slices in which callosal fibers projecting to OC1 or OC2 are preserved. Stimulation of the contralateral white matter resulted in EPSPs recorded in layer II/III and V cells of OC2 studied with intracellular recording. Current source density analysis of extracellular field potentials collected in OC1 and OC2 revealed laminar current sink patterns paralleling the laminar distribution of callosal terminations reported by Miller and Vogt (Dev. Brain Res., 14 (1984) 304-309). Exposure of slices to 2 mM kynurenic acid reversibly abolished current sinks in OC1 recorded in response to callosal stimulation indicating that glutamate receptors mediate the response of OC1 to callosal afferent activity. This new slicing technique can be readily adapted to study other systems in the nervous system in which neural processes follow curved trajectories.

Description
An account of the resource
Long-term potentiation (LTP), intensively studied in the hippocampus as a possible mnemonic device, has begun to be studied in the neocortex. In this study the effects of varying tetanic stimulus parameters on LTP of field potentials recorded from layer II/III induced by white matter stimulation in the in vitro rat visual cortical slice were examined. Low intensity tetanus was more effective in producing LTP than high-intensity tetanus, although single pulses of very high intensity reliably resulted in LTP. LTP consistently occurred following 2 Hz-60 min, or 100 Hz-10 min tetanus; whereas, 10 min of 7 and 25 Hz tetanus usually resulted in long-lasting depression. Although no obvious rule related tetanus frequency and duration to the incidence of LTP, an inverted-U relationship was found between tetanus frequency and LTP magnitude.
