functioning. Cognitive Functioning The cerebral cortex is divided into four lobes as well as into left and right hemispheres. Martinez (2010‚ pp.237) states that‚ “The cerebral cortex is the anatomical origin of the mind’s higher-order functions—reasoning‚ intelligence‚ creativity‚ and problem-solving—as well as the coordination of sensory input and motor control that helps us relate skillfully to our environments.” By segregating each structure of the cerebral cortex a greater understanding is achieved

The Five Major Structures of the Brain The brain is an amazing structure. It is the most complex and interesting part of the human body. It is like a huge computer that runs every function of the body. The brain is made up of the five major structures that include: the myelencephalon‚ metencephalon‚ mesencephalon‚ deicephalon‚ and the telencephalon. Each of these structures also has substructures involved within them. You start learning how to do things when you are born and keep learning as

B) The brainstem is responsible for higher level thinking skills. C) Damage to the brainstem is usually fatal. D) All twelve cranial nerves enter or exit from the brainstem.

The Cerebellum The second largest area‚ is responsible for maintaining balance and further control of movement and coordination. The Diencephalon The diencephalon or interbrain sits atop the brain stem and is enclosed by cerebral hemispheres. The major structure of the diencephalon are the thalamus‚ hypothalamus and

(Interactive transcripts are also available on the TED web site.) Based on what you have learned‚ which of Kurzweil’s predictions do you agree with‚ and which do you doubt? Why? Please be specific. I agree with Kurzweil’s predictions about the communications revolution. Kurzweil states that‚ “The

large areas of the brain have been found to be involved in speech processing. In more recent research‚ subcortical regions (those lying below the cerebral cortex such as the putamen and the caudate nucleus) as well as the pre-motor areas (BA 6) have received increased attention. It is now generally assumed that the following structures of the cerebral cortex near the primary and secondary auditory cortexes play a fundamental role in speech processing: * Superior temporal gyrus (STG):

The five major structures of the brain are myelencephalon‚ Metencephalon‚ mesencephalon‚ diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum
