Forget about page count and focus on word count. For a first novel, depending on genre (and assuming we are talking about trade publishing), you are looking at 80,000â90,000 words. If you are squeezing 700 words per page in MS Word on average, thatâs around 120 pages of MS Word, or 240 double-spaced, in TNR.
The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the dorsal portion of the frontal lobe.hough the Betz cells do not compose the entire motor output of the cortex, they nonetheless provide a clear marker for the primary motor cortex. This region of cortex, characterized by the presence of Betz cells, was termed area 4 by Brodmann.
Like all parts of the neocortex, the primary motor cortex is made of six layers (Figure 3.6). Unlike primary sensory areas, primary motor cortex is agranular cortex; that is, it does not have a cell-packed granular layer (layer 4).Instead, the most distinctive layer of primary motor cortex is its descending output layer (Layer 5), which contains the giant Betz cells. Primary motor cortex encodes the direction of movement. 2  Many neurons in the primary motor cortex are selective for a particular direction of movement. 3  For example, one cell may fire strongly when the hand is moved to the left, whereas it will be inhibited when the hand is moved to the right (Figure 3.8).
