The rule of 4 of the brainstem

... Once again we are assuming that the patient you are seeing has a brainstem problem, most likely a vascular lesion. The 4 S’s or ‘meridians of longitude’ will indicate that you are dealing with a lateral brainstem problem and the cranial nerves or ‘parallels of latitude’ will indicate whether the pro ...

... eating, and it is therefore important to understand the brain mechanisms involved in food reward, in order to understand the control of appetite and food intake. When the behavior is goaldirected, brain regions such as the cingulate cortex are likely to be engaged (see Fig. 1). However, it is a usef ...

This system may use syntactic processing to perform the planning, and is therefore part of a linguistic system which performs explicit (conscious) processing, as described more fully elsewhere (Rolls ...

... Tier 2 is that any learning in Tier 2 of the value of an object or face seen in one location on the retina, size, and view will generalize to other views etc. In rodents, there is no such clear separation of “what” from “value” representations. For example, in the taste system, satiety influences tas ...

... the foundations on which this answer was grounded. As I said earlier, MNs were first discovered in the ventral premotor area of macaque monkeys; more precisely, in the area F5. Some years before this discovery, single-cell recording experiments showed that the activity of F5 neurons is correlated wi ...

Two eye fields have been identified in the frontal lobes of primates: one is situated dorsomedially within the frontal cortex and will be referred to as the eye field within the dorsomedial frontal cortex ŽDMFC.; the other resides dorsolaterally within the frontal cortex and is commonly referred to ...

If you can remember these rules the diagnosis of brainstem vascular syndromes becomes a pitifully simple exercise (?!) – here’s how it works: In the rule of 4 there are 4 rules 1.

The perirhinal cortex was subdivided into three subregions: rostral (posterior to AP ⫺2.80 in relation to bregma; Paxinos & Watson, 1997), mid (posterior to AP ⫺3.80), and caudal (posterior to AP – 4.80). It should be noted that our rostral perirhinal measu ...

Dorsal Anterior Cingulate Cortex: A Bottom-Up View

... The function of the dorsal anterior cingulate cortex (dACC) is one of the major puzzles in cognitive and systems neuroscience. Papez (1937) classified the entire cingulum as part of the brain’s limbic system, thus linking the dACC with emotional processes. Early human lesion studies certainly suppor ...

Motor cortex



Motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements.Classically the motor cortex is an area of the frontal lobe located in the dorsal precentral gyrus immediately anterior to the central sulcus.
