The study of brain size is a poor way to study the evolution of intellect for the reason that brain size does not correlate well with intelligence within a species, but it can be with differences in intelligence between species through some adjustments for body size. One important characteristic relevant to the evolution of the brain and intelligence are modern humans’ brain size lacking in relation for an accurate explanation of intelligence without modifications being applied to it to exist. This idea was made by:
Jerison (1973) proposed that a ratio of body weight …show more content…
Sensory neurons will mostly have a bipolar shape (in the form of a pseudo-bipolar nerve) as the only structural variations that lack an axon and dendrite with only a single branch extending from the cell body. Bipolar and multipolar neurons do not have the exact same qualities as above given that bipolar ones have two branches for neuronal processes extending from the neural cell body in addition to a single axon and dendrite, “[where it can be] found in the retina of our eyes. In fact, during embryonic development, the eyes grow directly right out of the brain” (Antranik, 2012, para. 4). The latter shape happens to possess many branches extending from the cell body with a usual one axon and numerous dendrites as the shape for all motor neurons. On the other hand, interneurons (association neurons) is functional in its purpose to transmit impulses which are located exclusively within the central nervous system making up 99.8% of it. It is also responsible for memory, thinking, and decision-making in a typical multipolar shape. After all, these neurons are related in their categories as shapes …show more content…
These lobes are also named after the skull bones that lie above them. On the other hand, the cerebellum of the brain is a structure located in the metencephalon and part of the overall brain’s hindbrain which is nicknamed the, ““little brain”, is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance [to probably higher cognitive functions in humans]” (Patricia, 2012, para. 5). It is even concerned with some types of learning can use past experience to make corrections and automate behaviors, whether they involve motor systems or not. Given these points, the four major lobes and cerebellum of the brain certainly do have a load of functions for helping human beings with various necessary things for their entire
