Examples
This pathway leads from the hippocampus—a brain region that controls learning and memory—to the thalamus, which acts as a sort of sensory information relay station in the brain.
Researchers have long hypothesized that psychedelics may cause the thalamus to function less effectively, says Preller.
The thalamus sits in the center of the brain and processes information from the senses before sending relevant signals up to the cortex.
Then Preller and colleagues did a more targeted study, using fMRI data to look for changes in functional connectivity between the thalamus and the cortex.
In the predictive processing model, signals going down from the cortex to the thalamus would represent predictions, and signals flowing up to the cortex would represent errors.
Ganglia geniculata are found for the first time in connexion with the optic tracts in the lower part of the thalamus.
The cerebellum is a subsequent outgrowth from the medulla, as is the cerebrum and olfactive166 lobes from the thalamus.
These serve as nectaries, s, the whorl of stamens inserted on the thalamus and surrounding the pistil.
The thalamus and corpus striatum are called together, the great inferior ganglion of the brain.
The optic thalamus is indicated in the engraving, but the corpus striatum, being more exterior and anterior, does not appear.
