What term is used to refer to the fact that functions seen on one side of the body are controlled by the opposite cerebral hemisphere?
The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
What is the primary difference between transcranial magnetic stimulation TMS and transcranial direct current stimulation tDCS quizlet?
What is the primary difference between transcranial magnetic stimulation (TMS) and transcranial direct stimulation (tDCS)? tDCS generates a brief electrical current in the brain by generating magnetic pulses. TMS requires the patient to be asleep during administration, while tDCS does not.
What term is used to refer to the fact that functions seen on one side of the body are controlled by the opposite cerebral hemisphere quizlet?
What term is used to refer to the fact that functions seen on one side of the body are controlled by the opposite cerebral hemisphere? Contralateral representation. You may have heard different tissues in the brain being referred to as either “gray matter” or white matter.
How much information is visual?
In fact, the human brain processes images 60,000 times faster than text, and 90 percent of information transmitted to the brain is visual.
What might be a reason that a person might not see an advantage for their left hemisphere in this experiment?
What might be a reason that a person might not see an advantage for her or his left hemisphere in this experiment? The task was so easy that neither response time nor accuracy varied between the conditions.
What is behind the expression Use your gray matter and why is it not entirely accurate?
People use the expression “use your gray matter” when they want a person to think harder. The “gray matter” in this expression is probably a reference to the cerebral hemispheres more generally; the gray cortical sheet (the convoluted surface of the cortex) being the most visible.
What do transcranial direct current stimulation and transcranial magnetic stimulation have in common quizlet?
What do transcranial direct current stimulation and transcranial magnetic stimulation have in common? Both allow researchers to excite or inhibit neuron activity. Which of the following is an invasive way of imaging the brain? The actions that the researchers study are simple.
Why would it be accurate to say that neural communication is an electrochemical process ‘?
Why is neural communication sometimes described as an “electrochemical” process? a. The action potential is chemical, and transmission across the synapse is electrical. The action potential is electrical, and transmission across the synapse is chemical.
What makes white matter white?
myelin
It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.
