how many Neuron cells there are in our brain? a) 250 b) 100 billion c) 1 million A This is a required question 2. True or false: Do Neurons grow back if they ar a) Yes b) No c) It depends on when they were damaged 3. How much do you think your brain weighs? a) 0.5-1.0kgs(1.1-2.2lbs) b) 1.1-1.3kgs(2.3-2.9lbs) c) 5-6kgs(11-13lbs) 4. If a person fell and damaged their occipital lol affected? a) Taste b) Smell c) Vision d) Touch

Answer 1

1. **b) 100 billion** While the precise number is difficult to pinpoint and some estimates vary, the generally accepted approximation is around 86 billion neurons. 100 billion is the closest option provided.2. **c) It depends on when they were damaged.** Neurogenesis (the birth of new neurons) does occur in certain brain regions throughout adulthood, but the capacity for regrowth and repair after damage is limited and depends on factors like the area of the brain affected, the extent of the damage, and the age of the individual.3. **b) 1.1-1.3kgs (2.3-2.9lbs)** The average adult human brain weighs approximately 1.2-1.4 kg (2.6-3.1 lbs). The option provided that is closest to this range is 1.1-1.3kgs (2.3-2.9lbs).4. **c) Vision** The occipital lobe is the primary visual processing center of the brain. Damage to this area can result in various visual impairments, including blindness or difficulty interpreting visual information.
