Long-term potentiation (LTP) is an important mechanism thought to mediate changes in synaptic connectivity following various types of experience. We examined the effects of visual discrimination training on LTP in the mature, rodent thalamocortical visual system. Adult rats underwent visual discrimination training in a modified Morris Water Maze containing(More)
The rodent primary visual cortex (V1) is densely innervated by serotonergic axons and previous in vitro work has shown that serotonin (5-HT) can modulate plasticity (e.g., long-term potentiation (LTP)) at V1 synapses. However, little work has examined the effects of 5-HT on LTP under in vivo conditions. We examined the role of 5-HT on LTP in V1 elicited by(More)
Cholinergic projections originating in the basal forebrain (BF) play important roles in the heterosynaptic facilitation of synaptic strength in various sensory cortices, including the primary visual cortex (V1). Here, using urethane-anesthetized rats, we find that pairing burst stimulation of the BF with single pulse stimulation of the lateral geniculate(More)
