The allocortex (also known as heterogenetic cortex) is one of two types in the cerebral cortex, the other being the neocortex. It is characterized by having just three or four cell layers, in contrast with the six layers of the neocortex, and takes up a much smaller area than the neocortex.
The neocortex, also called the neopallium and isocortex, is the part of the mammalian brain involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning and language.
how does the neocortex work? The neocortex is part of the cerebral cortex (along with the archicortex and paleocortex - which are cortical parts of the limbic system). It is involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, conscious thought, and in humans, language.
The paleocortex includes the piriform lobe, specialized for olfaction, and the entorhinal cortex. The archicortex consists of the hippocampus, which is a three-layered cortex dealing with encoding declarative memory and spatial functions. The neocortex represents the great majority of the cerebral cortex.
The difference is neocortex has 6 horizontal layers of different neuronal structure, while the rest of cortex, called "allocortex" has 3 layers. They all constitute a single sheet of gray matter, and in humans neocortex is almost whole of it, while allocortex areas are somewhere at the boundaries.

Among the many structures of the dog's brain, the hippocampus plays several important roles. This structure also helps your dog navigate so he can find his way through the doggy door and it helps your dog form emotional reactions along with several other important cognitive functions.
The prefrontal cortex is a part of the brain located at the front of the frontal lobe. It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.
Our reptilian brain includes the main structures found in a reptile's brain: the brainstem and the cerebellum. The neocortex first assumed importance in primates and culminated in the human brain with its two large cerebral hemispheres that play such a dominant role.
Showing six layers of cerebral cortex of control group; molecular layer (I), outer granular layer (II), outer pyramidal layer (III), inner granular layer (IV), inner pyramidal layer (V) and polymorphic layer (VI).
Association areas: parts of the cerebral cortex that receive inputs from multiple areas; association areas integrate incoming sensory information, and also form connections between sensory and motor areas.
Emotions, like fear and love, are carried out by the limbic system, which is located in the temporal lobe. While the limbic system is made up of multiple parts of the brain, the center of emotional processing is the amygdala, which receives input from other brain functions, like memory and attention.
Cortex means "bark" in Latin and appropriately the cerebral cortex is the outermost layer of the brain, made up primarily of grey matter. It is the most prominent visible feature of the human brain, and although it is only a few millimeters thick, it comprises about half of the weight of the brain.
The complexity of neocortex emerges during development through a process called arealization, when specific sensory and motor functional areas are formed and connected to one another and to sub-cortical nuclei through a vast and complex network of intra- and extra-neocortical connections.
To conclude, the reason they call the brain stem reptilian brain, is because it represents the oldest and most primitive part of our brain. The one we share with simpler organisms, like reptilians.
Dolphins also have a very complex neocortex, the part of the brain responsible for problem-solving, self-awareness, and variety of other traits we associate with human intelligence. They can recognize themselves in a mirror (a feat most animals fail at—and a sign of self-awareness).
The frontal lobe, occipital lobe, temporal lobe and parietal lobe make up the cerebrum. The frontal lobe is responsible for problem-solving, voluntary body movement, sentence formation and personality. The occipital lobe is where processing of visual information takes place.
The limbic system is a set of structures in the brain that controls emotion, memories and arousal. It contains regions that detect fear, control bodily functions and perceive sensory information (among other things).
Poor cerebral cortex functions leads to more impulsive behavior. Study subjects in whom the activity of the prefrontal cortex was temporarily suppressed could control their emotional impulses less well than normal. Their amygdala deep in the brain that is responsible for emotional reactions then becomes extra active.
The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. This sensation is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
