Brains II

In the top half up front, the anterior nucleus has many cingulate gyrus PATHWAYS going both ways. Below that we see the ventral anterior nucleus (yellow), the ventrolateral nucleus (red), then the ventro posterolateral nucleus is in the back (these are all lateral). Two bumps at the back the geniculate nuclei Lateral is the [optical, SEEN IN GRAY] lateral geniculate which send along to the midbrain superior colliculus. More medial to the last are the medial geniculates which communicate with the inferior colliculli (auditory) on the mid brain just distal to the visual superior coliculi. On each of the medial surfaces – more forward - is the dorsomedial nucleus. Then behind that the large “pulvinar”(light blue”). The pulvinar is the largest portion of the thalmus. It can be amiss in blind sight. It also figures in visual attention. OK – a visuar thingy. But it has something to do with social recognition and sensibility. It juggles the various senses to establish a consensus of the senses. This includes getting attention to what is playing in the visual cortex. Somehow schizophrenia, autism, and prion disorders.
