Traumatic brain injuries (TBIs) are a leading cause of morbidity, mortality, disability and socioeconomic losses in India and other developing countries. It is estimated that nearly 1.5 to 2 million persons are injured and 1 million succumb to death every year in India. Road traffic injuries are the leading cause (60%) of TBIs followed by falls (20%-25%) and violence (10%). Alcohol involvement is known to be present among 15%-20% of TBIs at the time of injury. The rehabilitation needs of brain injured

part. Research, though little has been conducted, suggests that migraines may be caused by changes occurring within the brainstem and its interactions with a major pain pathway called the trigeminal nerve. A current theory is that an imbalance in brain chemicals such as serotonin, a pain regulating chemical, may also contribute to these severe headaches. During a migraine attack, serotonin levels may drop, which can cause the trigeminal nerve to release neuropeptides that travel throughout the brain's

The nervous system of a crayfish contains a ventral nerve cord. This nerve cord transmits signals to the ganglion cells. The ganglion cells are in the tail of the crayfish in which it controls the muscles of the tail as well. The anatomy of the crayfish is simple yet all of its functions are important to their day-to-day lives. They are mainly composed of extensor muscles, gonads, hearts, encephalon, stomach, eyes, green gland, mouth, mandible, esophagus, maxilliped, ventral nerve cord, and ganglion

Figure 5A shows examples of the magnitudes of visual responses to the same set of stimuli in a similar pair of upper layer neurons and the CCG obtained from the pair for each experimental group. To relate response similarity with the degree of synchronized firing, the signal correlation values were separated into 4 ranges according to the magnitude of the values, and the mean CCG peak area calculated for each range was plotted in Figure 5B. At P13-15, the CCG peak area very slightly increased with
