The amygdaloid region of the brain (i.e. the amygdala) is a complex structure involved in a wide range of normal behavioral functions and psychiatric conditions. The hormone of love. "The hormone best known for its role in inducing labor may influence our ability to bond with others, according to researchers at the University of California, San Francisco.
In a preliminary study, the hormone oxytocin was shown to be associated with the ability to maintain healthy interpersonal relationships and healthy psychological boundaries with other people. The study appears in the July issue of Psychiatry. "This is one of the first looks into the biological basis for human attachment and bonding," said Rebecca Turner, PhD, UCSF adjunct assistant professor of psychiatry and lead author of the study. "Our study indicates that oxytocin may be mediating emotional experiences in close relationships. " Shelf for Brain Science Podcast (showing 1-20 of 72) Brain Fitness & Brain Training.

C. George Boeree. Acetylcholine neurotransmitter supplements that increase levels naturally. Neurotransmitters - Chemistry Encyclopedia - structure, proteins, molecule, General Mechanism of Action. Photo by: 3drenderings Neurotransmitters are chemical messengers produced by the nervous systems of higher organisms in order to relay a nerve impulse from one cell to another cell.
The two cells may be nerve cells, also called neurons, or one of the cells may be a different type, such as a muscle or gland cell. A chemical messenger is necessary for rapid communication between cells if there are small gaps of 20 to 50 nanometers (7.874 × 10 −7 –19.69 ×10 −7 inches), called synapses or synaptic clefts, between the two cells. List all the essential neurotransmitters. Acetylcholine - synthesized from Choline, Lecithin, and panthothenic acid (B5), or Diethylaminoethanol (DMAE)
Acetylcholine - Chemistry Encyclopedia - structure, reaction. Photo by: RAJ CREATIONZS Acetylcholine is the neurotransmitter produced by neurons referred to as cholinergic neurons.
In the peripheral nervous system acetylcholine plays a role in skeletal muscle movement, as well as in the regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved in learning, memory, and mood. The Silva Method Centering Exercise. Neuron. All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium.
Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives. Neurons do not undergo cell division. In most cases, neurons are generated by special types of stem cells. A type of glial cell, called astrocytes (named for being somewhat star-shaped), have also been observed to turn into neurons by virtue of the stem cell characteristic pluripotency.
Overview[edit] Anatomy and histology[edit] Memory and the Human Lifespan. If all of these memories were gone, would "self" even have a meaning?
The truth is that while you may think of human memory as a capacity—a way to call up important facts or episodes from your past—it is much, much more. Your various memory systems, in fact, provide the continuity of consciousness that allows the concept of "you" to make sense, creating the ongoing narrative that makes your life truly yours. Without those systems and the overall experience of memory they make possible, you would have no context for the most crucial decisions of your life. You would have to make—without the benefit of experience and knowledge—the decisions that determine not only your quality of life, but your very survival. And your ability to learn, or even to form the personality that makes you unique, would similarly be set adrift.
His 24 riveting lectures carefully explain. Understanding the Brain. You Love Your iPhone. Literally. But should we really characterize the intense consumer devotion to the iPhone as an addiction?
A recent experiment that I carried out using neuroimaging technology suggests that drug-related terms like “addiction” and “fix” aren’t as scientifically accurate as a word we use to describe our most cherished personal relationships. That word is “love.” As a branding consultant, I have followed Apple from its early days as a cult brand to its position today as one of the most valuable, widely admired companies on earth. A few years back, I conducted an experiment to examine the similarities between some of the world’s strongest brands and the world’s greatest religions. Using functional magnetic resonance imaging (fMRI) tests, my team looked at subjects’ brain activity as they viewed consumer images involving brands like Apple and Harley-Davidson and religious images like rosary beads and a photo of the pope.
So are our smartphones addictive, medically speaking? Brain Grade - Lumosity.
