The Brain Brainstem The brain stem plays an important role in basic attention‚ arousal‚ and consciousness. It contains the medulla oblongata‚ cerebellum‚ midbrain and pons. Its functions include things that you need to survive‚ such as breathing‚ digestion‚ heart rate‚ blood pressure‚ and arousal which makes you awake and alert.All information from our body passes through the brain stem on the way to the brain. Medulla Oblangata The medulla oblongata connects the brain and spinal cord.

Introduction: Empathy‚ the ability to recognize and share feelings of others‚ has been in our brains since the beginning of time. It was discovered by the Greeks which they called it ‚ “Empatheia” meaning‚ “in feeling.” Then a German psychologist named Robert Vischer in 1837 and he called it “Einfühlung‚” meaning “feeling into.”(Stueber‚ 2013) Vischer wrote a book called‚ “Über das opstiche Formgefühl: Ein Beitrag zu Aesthetik.”(Schott‚ 2015) In this book Vischer describes how empathy is based

Mirrors in the Brain On a 1991 hot summer day in Parma‚ Italy‚ a lab monkey awaited its researchers’ return from lunch. The researchers had implanted wires next to its motor cortex‚ in a frontal lobe brain region that enabled the monkey to plan and enact movements. The monitoring device would alert the researchers to activity in that region of the monkey’s brain. When the monkey moved a peanut into its mouth‚ for example‚ the device would buzz. That day‚ as one of the researchers entered the lab

The brain itself requires extremely fast speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration of a single neuron with major structures labeled. Panel B is an illustration of a cross section of a neuron that

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

nervous and endocrine system and how they interact to send messages to the brain so it can then be transfurred to the different parts of the body to respond. All the parts of the brain‚ and what parts control which parts of your body‚ memory‚ vision‚ and how it works. The effects on the brain when separated into two hemispheres. We also saw images of the brain through EEG‚ CT scan‚ MRI‚ PET‚ and F MRI. All ways to look at the brain and its activity. The most interesting part of the chapter for me it

The Brain Brittany Wagner Psy/240 June 22‚ 2014 Jennifer Graves The Brain The brain is like a hard drive for a computer. Like a hard drive the brain also has many wires and complicated looking things in there. It is a lot easier to understand what part of the brain does what when it is broken down into the five major parts. The brain has five major parts and each part helps the human body function. The five major parts are called the myelencephalon‚ metencephalon‚ mesencephalon‚ diencephalon

In the documentary multiple unique qualities of the brain are explored‚ studied‚ and tested to determine how we can benefit from understanding the functions of the brain. Learning about the fundamentals of the brain in the text made understanding the procedures our brain undergoes to process information‚ react

Are the brains of men and women specialized in different ways to achieve the same capabilities? Many studies are showing that the brains of men and women may be specialized in different ways to achieve the same capabilities. An example of this would be a man’s brain using one part of the brain to accomplish a task and a woman’s brain accomplishing the same task with another part of the brain. Based on the text I believe that the brains of men and women are specialized in different ways. One example
