Document Summary
Transmission vs bursting mode transmission or bursting mode. The resting membrane potential of the neuron determines whether a thalamic neuron will fire in: hyperpolarizing: fire in bursting mode (more negative than -65 mv) Underlying mechanism seems to aim to block information transmission. During slow wave sleep: eeg recordings exhibit low-amplitude, high frequency, asynchronous activity, shift to large amplitude, slow (0. 5 4 hz) oscillations. Delta waves transition from wakefulness to slow wave sleep. Thin sheet located laterally on the thalamus. Negative feedback on thalamic nuclei based on thalamic and cortical inputs. Faster (7-14 hz) eeg oscillations that are periodically super imposed on the. Massive radiation of white matter fibers that connect the thalamus to the cortex and vice-versa. When the fibers fan out from the internal capsule, we call it the coronal radiata . Divided into anterior and posterior limbs: thalamus is always next to the posterior limb (not to be confused with the caudate which lines the anterior limb)
