Brain Parts

As you proceed up the evolutionary ladder from fish toward humans, check out the changes in the brain. 

For example, the cerebrum gets bigger, takes up a larger part of the total brain and becomes folded.

The simplest possible creatures have incredibly basic nervous systems made up of nothing but reflex pathways.

For example, flatworms and invertebrates don’t have centralized brains. They have loose associations of neurons arranged in straightforward reflex pathways.

Flatworms have neural nets, or individual neurons linked together that form a net around the entire animal.

Most invertebrates (such as the lobster) have modest “brains” that consist of localized collections of neuronal cell bodies called ganglia. Each ganglion controls sensory and motor functions in its segment through reflex pathways, and the ganglia are linked together to form a simple nervous system. As nervous systems evolved, chains of ganglia evolved into more centralized simple brains.

Brains evolved from ganglia of invertebrates. Regardless of the animal, brains have the following parts:

The brain stem, which consists of the medulla (an enlarged portion of the upper spinal cord), pons and midbrain (lower animals have only a medulla). 

The brain stem controls the reflexes and automatic functions (heart rate, blood pressure), limb movements and visceral functions (digestion, urination).

The cerebellum integrates information from the vestibular system that indicates position and movement and uses this data to coordinate limb movements.

The hypothalamus and pituitary gland are responsible for visceral functions, body temperature and behavioral responses such as feeding, drinking, sexual response, aggression and pleasure.

The cerebrum (also called the cerebral cortex or just the cortex) consists of the cortex, large fiber tracts (corpus callosum) and some deeper structures (basal ganglia, amygdala and hippocampus). 

It integrates info from all of the sense organs, initiates motor functions, controls emotions and holds memory and thought processes (emotional expression and thinking are more prevalent in higher mammals).


Feminine brain ?

Good and God’s morning ….. 

Know where to find the information and how to use it – That’s the secret of success.
(Albert Einstein Quote) 

feminine brain

so how about mind of women and mind of God …..

today is my date to update my page …..Mind of God ……once we understand mind of God ….we can understand mind of a women ….. as both are feminine in nature …. 

and recently I was talking to a friend who heads a large information technology education institute so asked him ……what is the foremost problem of modern times and his reply was ……..management of information ……

and as internet has grown out of proportion …..on every subject there are millions and millions pages …..so it is another problem how to search it …..

so told him why we can not design the super computers on the basis of how our brain works ….. 

human brain is a super computer and at present we are learning more about scientific findings on this page …… brain is our super friend so is our mind and so is mind of God ….. and these all machines are very complex but all are users friendly …..

like machines inside a car …..normal human can not understand but we all can drive with simple understanding of operating it …… 

later in this series we will understand how to operate our brain and mind …… so go through this series and at last we all comes to know how simple and friendly is our brain ,mind and mind of God …..so also a feminine mind …

if you have total freedom to share my pages and if you think it make sense to you …… share it with more friends …… 

sharing is one of the quality of Mind of God and ….. be a mind of God …..share love , peace , silence , happiness ,…….they all comes to you because of sharing ….. 

sharing is feminine …..

with love and gratitude to God and to all my friends everywhere

love all.

Basic Neuron Types


Meet the neurons!

Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters.

They also have different shapes depending on their functions. Motor neurons that control musclecontractions have a cell body on one end, a long axon in the middle and dendrites on the other end. Sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle. Interneurons, orassociative neurons, carry information between motor and sensory neurons.

These fundamental members of the nervous system also vary with respect to their functions.

  • Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system.
  • Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body.
  • Interneurons connect various neurons within the brain and spinal cord.

The simplest type of neural pathway is a monosynaptic (single connection) reflex pathway, like the knee-jerk reflex. When the doctor taps the right spot on your knee with a rubber hammer, receptors send a signal into the spinal cord through a sensory neuron. The sensory neuron passes the message to a motor neuron that controls your leg muscles. Nerve impulses travel down the motor neuron and stimulate the appropriate leg muscle to contract. The response is a muscular jerk that happens quickly and does not involve your brain. Humans have lots of hardwired reflexes like this, but as tasks become more complex, the pathway circuitry gets more complicated and the brain gets involved.
