Answer:
If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.
Explanation:
Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.
- <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
- An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.
An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.
On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.
The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

The amygdala is found in each temporal lobe and is involved with the limbic system. The amygdala is found in the medial temporal lobe, immediately prior to the hippocampus. The temporal lobes are the second biggest lobes, located behind the ears. They are most typically related with the processing of auditory information and memory encoding.
The temporal lobes' primary roles include language comprehension, memory acquisition, face recognition, object recognition, perception, and auditory information processing amygdala. The temporal lobe is in charge of understanding and assigning meaning to different sounds. As a result, injury to the left temporal lobe often leads to issues understanding language.

Answer:
The correct answer is: enhanced zones of inhibition in the area between two adjacent disks.
Explanation:
- According to the question, the two antibiotics show the property of Synergism.
- Synergism can be defined as the property of two drugs, where the efficiency of activity (killing the bacteria) obtained on using the two drugs together is far more than the efficiency obtained by using individual drugs separately.
- In the disk diffusion method, the efficiency in activity (killing of bacteria) of two drugs is determined by plating a nutrient agar media with the particular target bacteria and adding the two antibiotics in two discs separated from each other by a certain distance.
- Both the antibiotics diffuse into the agar media from the discs and kill the target bacteria.
- Zone of inhibition can be defined as the circular clear zone on the nutrient agar plate obtained after allowing the bacteria to grow for the required period of time. This is the region where no bacteria grow as they are killed by the antibiotics used.
- Depending upon the efficiency of the antibiotic used and also its ability to diffuse into the nutrient agar medium, bacteria tends to grow near the periphery of the nutrient agar plate where the antibiotic fails to reach.
- In the question, as the two antibiotics used show synergistic effect, the region on the nutrient agar plate in between the two discs, where both the antibiotics are able to percolate will show a larger zone of inhibition.
