What lobe of the brain is associated with the processing and interpreting of visual stimuli?
Answer Choices:
A. Frontal lobe
B. Occipital lobe
C. Parietal lobe
D. Temporal lobe


The occipital lobe is the primary visual processing center. It receives visual input from the retina and interpret the signal into a recognizable image. While the parietal lobe and temporal lobe are also involved in visual perception, their main role differ. The parietal lobe primarily processes sensory information such as touch, temperature and taste and the temporal lobe processes sound, noise, speech and the recognition of auditory stimuli. The frontal lobe is mainly associated with reasoning, emotions, planning and problem solving.

Estrogen is the primary female sex hormone, while testosterone is for the male. Among its many effects in the body, estrogen is mainly released during puberty to initiate development of female secondary sex features (e.g. breast, pubic hair) and progesterone is highly active during ovulation to help thicken the uterus lining in preparation for pregnancy. Thymopoietin is the hormone released by the thymus to stimulate the growth of T-lymphocyte cells and the melatonin hormone is produced by the pineal gland to help control the circadian sleep-wake
