The thalamus then relays that information to the neocortex (the “thinking brain”). Rather than simply measuring raw brain weight, the EQ formula makes for a ranking of animals. When you see, hear, touch, or taste something, that sensory information first heads to the thalamus, which acts as your brain's relay station. Many scientists believe that the entire brain is involved with memory. By that measure, human brains, by comparison, are seven times average. The brain stem relays sensory information between the spinal cord and the parietal lobe, such as temperature, pain and spatial awareness. The brain stem also controls involuntary body functions. It guides eye and head movements and a person’s sense of orientation. They have argued that memory is located in specific parts of the brain, and specific neurons can be recognized for their involvement in forming memories. The thicker the corpus callosum, the more efficiently the brain synchronizes its activities. It is located in the head, usually close to the sensory organs for senses such as vision.It is the most complex organ in a vertebrate's body. Researchers have studied what part of the brain controls speech, and now we know much more. Intelligence in animals is hard to establish, but the larger the brain is relative to the body, the more brain weight might be available for complex cognitive tasks. T he biological basis for variations in human intelligence is not well understood, but research in neuroscience, psychology, and other fields has begun to yield insights into what may undergird such differences. The brain is the most complex part of the human body. (Hirsch, WE-IQ TV Interview with Judith E. Glaser, May 1, 2018). One well-known hypothesis, backed by evidence from brain scans and studies of people with brain lesions, proposes that intelligence is seated in particular clusters of … However, since Lashley’s research, other scientists have been able to look more closely at the brain and memory. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. The premotor cortex is a region found beside the primary motor cortex. A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It’s the part of the brain that’s responsible for behavioral and emotional responses. The limbic system is a group of interconnected structures located deep within the brain. From there, it is sent to the amygdala (the “emotional brain”) which produces the appropriate emotional response.

When we listen to connect, we activate Wernicke’s area: the part of the brain that allows us to comprehend spoken language.

The prefrontal cortex plays an important part in memory, intelligence, concentration, temper and personality. The corpus callosum, the part of the brain that connects the two lobes, is thicker in diameter in people who score highly on creativity tests. Lying in its bony shell and washed by protective fluid, the brain is the source of all the qualities that define our humanity. The brain stem is part of the hindbrain along with the cerebellum and extends down toward the spinal cord.
