When it comes to the brain and IQ, is bigger better? Does size really matter? Is there really a connection between the size of your brain and intelligence? With the help of findings by neurologists and scientists, we seek to find out!
- Ailments and the brain: Scientists have found that children with autism have a brain that has grown in a disproportionate manner in the very first year of their life. This prevents the child from making connection in a normal manner. On the other hand, children and adolescents who suffer from Attention Deficit Hyperactivity Disorder or ADHD show sign of having a much smaller brain size. Many scientists have shown that the size of the brain shrinks as we age and this does not have any visible effect on our cognitive abilities.
- It’s all relative: The size of the brain does not really have a bearing on the way a person’s cognition gets shaped. Even large mammals like elephants and whales are finally hunted and tamed by humans who have smaller brains in comparison. The brain is made up of billions of neurons, which need to function properly. It may be seen that scientists consider the brain mass in relation with the rest of the body so as to speculate about the cognitive abilities of the person. Why is this required? Large animals need a well functioning and proportionate brain size to control and run their organs with proper cognition for satisfactory results, which is what we humans seem to have done.
- Neanderthal brain: Historically, the earliest man or the Neanderthals are said to have had larger brains than we do. These people are believed to have brains that are at least 10% larger than the brains that we have in our modern times. The shape of their brain was different too. They were also heavily muscled people which had a bearing on the size and shape of the brain and bodies as well as the lean tissue within the brain. They also survived very successfully for a period of over 200,000 years, which obviously points to some form of elevated cognition, as per many scientists.
- Animals: While animals with small brains like lizards and reptiles do not perform too well on IQ tests, the animals with bigger brains like elephants and dolphins perform much better. But the medium sized brain of monkeys, lemurs and other animals are said to perform in the best manner. The correlation between the body size and the brain does not seem to hold good here, as per various researches.
So the verdict as per medical science and research stands divided! If you wish to discuss about any specific problem, you can consult a Neurologist.
Getting Hallucinations is a mental condition where a person sees, feels, hears, and tastes things that actually don't exist beyond one's heightened imagination or delusion. It involves the experience of perceiving something not present. Hallucinations can be pleasing or frightening. However, there is almost always an identifiable cause behind it.
They can be triggered by:
- Taking hallucinogenic or psychotropic substances
- Mental conditions like dementia and schizophrenia
- Neurological conditions like Alzheimer's disease or Parkinson's disease
- Macular degeneration, leading to loss of vision
- Migraines and brain tumor can also lead to such delusions
Some of the signs of hallucinations:
- Hearing voices: The medical term for hearing voices is called an 'auditory hallucination'. A person may sense sounds or noises coming from inside or outside of their mind. The noise might be random or disrupting. One might also feel the voices talking to each other or trying to tell them something. Most of the times, these voices come from inside the person's mind; or in some cases, one's heightened perception may make a normal noise delusional.
- Seeing things: This is also called visual hallucinations. For instance, one may see unnatural things like a floating chair in thin air. It all depends on a person's perception. Sometimes these hallucinations appear as bright flashy spots or rays of light.
- False sense of taste and smell: Technically these are known as gustatory and olfactory hallucinations respectively. One may feel a kind of odor coming from one's body or surrounding; or a person might feel that something he/she is drinking or eating has an odd taste. This is again heightened mal-perception causing delusional sensory activities.
- Tactile hallucinations: This is when a person feels things that don't exist. One may feel that he/she is being touched or tickled even when no one else is around or that insects are crawling beneath the skin. One may experience strange sensations, which are not a part of a reality. If you wish to discuss about any specific problem, you can consult a Neurologist.
