Learning to learn: Theta oscillations predict new learning, which enhances related learning and neurogenesis
2012
Animals in the natural world continuously encounter learning experiences of varying degrees of novelty. New neurons in the hippocampus are especially responsive to learning associations between novel events and more cells survive if a novel and challenging task is learned. One might wonder whether new neurons would be rescued from death upon each new learning experience or whether there is an internal control system that limits the number of cells that are retained as a function of learning. In this experiment, it was hypothesized that learning a task that was similar in content to one already learned previously would not increase cell survival. We further hypothesized that in situations in…
Rapid changes in bodily and neural states affect learning

Declarative memories consist of the past events and factual information that can be recalled. One of the most popular experimental paradigms used in studying long-term memory formation is classical conditioning. Trace conditioning is a hippocampus-dependent task where two separate sensory stimuli are presented in contingency but with a temporal gap between. In trace eyeblink conditioning a conditioned stimulus, usually a tone, is presented with a short silent period followed by an airpuff to the eye. In the beginning of the learning process the behavioral response to the airpuff is naturally a blink of an eye. After repeated trials the subject learns to shut the eyelid after perceiving the …
