One common test of language lateralization is invasive; it involves injecting ____________ into the carotid artery.
vova2212 [387]

Answer:

barbiturate/sedatives

Explanation:

Lateralization is a process of studying the split functions of the brain hemispheres. The most common test used for testing lateralization is obtained from sodium amytal studies. In this study a barbiturate or a sedative is injected into the carotid artery either left or the right artery. So, till the time the barbiturate hampers the functioning of any hemisphere, the functions associated with that hemisphere also gets hampered or are sustained for a while. This technique is of invasive nature

<h3>What are identical twins?</h3>

Identical twins refer to individuals produced by the same zygote cell, i.e., they are monozygotic twins.

Since these individuals are produced by the same zygote cell, their genetic material (DNA) will be identical.

Identical twins are useful to understand the exact role of genetics and environment in a given phenotypic trait.

Yuki888 [10]

Answer:

Simple cell

Explanation:

Simple cells are found in primary visual cortex and are made up of large number of receptive fields from neurons and the respond to light at specific Orientation and oriented edges. The cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. The simple cells respond to stimuli with some particular orientations to objects within their receptive fields. Receptive fields comprises of sensory receptors in the sensory neurons that draw out neurosonal responses when there are stimulated
