ASTROCYTES

        

Main role:

1. Enshesth synapses, regulate neural excitability and synaptic transmission.
2. Respond to injury by secreting extra cellular matrix proteins.
3. Implicated in Neuro Genesis, cell migration and many neurological and Psychiatric disorders.
4. Regulate the transmission of electrical signals across synapses by modifying the concentration of extra cellular potassium; Controlling local blood flow, releasing and taking up neuro transmitters and other Neuro modulatory substances, delivering nutrients to neurons, and altering the Geometry and volume of space between brain cells. All these things influence nervous system, communication and plasticity.
5.  Astrocytes have anatomical and physiological properties that may impose higher- order organization on information processing in the brain. In the gray matter of the cerebral cortex and Hypocampus, Astrocytes are organized in non overlaping domains.
6. The largest cell body, had been found to stop up extra neurotransmitter molecules around neurons, there by protecting nerve cells from receiving too much stimulation.
7.  A fatty complex called APOE/Cholestrol and the protein Thrombospondin, these two chemicals are released by astrocytes to stimulate synapsys formation.
8. Astrocytes might contribute to  a greater capacity for learning.
9.  Neurons are like telephone communicating electrically through hard wired synaptic connections, Astrocytes may be like cell phones communicating with chemical signals that broadcast widely but can be detected only by other astrocytes.
10. Astrocytes have listening ability.

This practise requires minimum one year. In every practise Rewrite the paper for minimum 5 times, understanding the functions of the astrocytes. Practise meditation on your’s A 25 for 5 minutes. 30 minits Visualize the functions of Astrocytes in your Prefrontal cortex-Brain Insula-White matter-Neuron-Synapses junction- Astrocytes coverage. Functions- Ferrying, Ion exchange, Neurotransmitter maintenance, Releasing ATP, Listening ability etc.  (Contd… 18)

TAIL- WAGGING- THE- DOG - 1

TAIL WAGGING THE DOG ! – I

Hai Friends,

TAIL WAGGING THE DOG !

Dog wagging the tail is real, but tail wagging the dog is unreal.  Meditation is only a brain exercise, it improves brain inner conditions i.e. Neurons, Neuro Transmitters, BDNF, Neuro Genesis etc.,  A Dog’s tail can be used for its social and physical needs.  Dog can use its tail to communicate, balance for swimming, warmth, and to keep insects away.  As a part of the dog’s spinal column, the Dog’s tail is veed for balance.  Yogi’s invented the mediation to improve people’s brains plasticity and consciousness.  Real Yogi never shows any magics and fantasy illusions.  They think reality, live in reality, speaks reality, preaches reality.   Indian’s top most yogi Vemana says “Make your life gold, but don’t waste your life in thriving for the gold”.   So always leads yours life with scientific realities and make yours life gold. 

• People in a positive mood had more ACC (Anterior Cingulate Cortex – A25) Activity going to the task, which probably helped prepare the brain to find novel solutions.
• The Amygdale helps us navigate the fine boundary between approach and avoidance.
• Glutamate drives a brain circuit involved in making decisions that are associated with positive outcomes.
• Microglia may also release immune chemicals called cytokines that control activity at neural junctions known as synapses.
• Astrocytes are in a position to control the balance between mental health and madness.
• Glia Cells are the working horses.
• Certain brain regions become Hyperactive during a panic attack the amygdala, our fear centers, and parts of the midbrain that control our feelings of pain.
• Music lessons, as with learning a second languaged, might stave off age-related cognitive decline.
• People can reap some of the benefits of the mediation without extensive of training.  Meditation by activating multiple brain areas can relive pains, pill-free analgesia.
• Memories of practical skills are barely effected by stress.
