Trace conditioning and extinction learning depend on the hippocampus. but it remains unclear how neural activity in the hippocampus is modulated during these two different behavioral processes. To explore this question. we performed calcium imaging from a large number of individual CA1 neurons during both trace eye-blink conditioning and subsequent extinction learning in mice. https://www.bekindtopets.com/special-pick-Grandpa-s-Best-Prairie-Hay-quick-pick/
