Ten of the most influential social psychology experiments explain why we sometimes do dumb or irrational things. “I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures.Why do good people sometimes act evil? Why do smart people sometimes do dumb or irrational things?” –Philip Zimbardo Like famous social psychologist Professor Philip Zimbardo (author of The Lucifer Effect: Understanding How Good People Turn Evil), I’m also obsessed with why we do dumb or irrational things.
The answer quite often is because of other people — something social psychologists have comprehensively shown. Each of the 10 brilliant social psychology experiments below tells a unique, insightful story relevant to all our lives, every day. Click the link in each social psychology experiment to get the full description and explanation of each phenomenon. 1.

Part I: Exploring photography in art and in science | Nervous Encounter. With photography as her principal medium, Melanie King has used A Nervous Encounter as an opportunity to explore new photographic techniques, while exploring neuroscience. Aligning neatly with this interest is the imagery produced by transmission electron microscopy (EM), used in the Basal Ganglia lab to visualise samples at extremely high magnifications. Instead of visible light, a beam of electrons inside a vacuum is transmitted through a very thin sample creating a shadow of the cellular membranes. A synapse is where two neurons communicate. Neurotransmitters are released from storage vesicles in a presynaptic neuron, pass across cell membranes and cause a cellular response in the neighbouring postsynaptic neuron. This structure and process, often depicted in textbook cartoons (such as on the left), can actually be visualised in the high magnification images produced by transmission EM (such as on the right).

Researchers at Carnegie Mellon have examined the function of neuron diversity and discovered that diversity is vital to comprehensive brain function. The study explored how specific neurons process complex stimuli and code information. Neuronal diversity makes a difference, says Carnegie Mellon study Heterogeneous groups of neurons transmit twice as much information as homogeneous groups Much like snowflakes, no two neurons are exactly alike.
But it’s not the size or shape that sets one neuron apart from another, it’s the way it responds to incoming stimuli. Carnegie Mellon University researchers have discovered that this diversity is critical to overall brain function and essential in how neurons process complex stimuli and code information. “I think neuroscientists have, at an intuitive level, recognized the variability between neurons, but we swept it under the rug because we didn’t consider that diversity could be a feature. “Diversity is an intrinsic good,” Urban said.

Jack and Beverly Wilgus, collectors of vintage photographs, no longer recall how they came by the 19th-century daguerreotype of a disfigured yet still-handsome man.
It was at least 30 years ago. The photograph offered no clues as to where or precisely when it had been taken, who the man was or why he was holding a tapered rod. But the Wilguses speculated that the rod might be a harpoon, and the man’s closed eye and scarred brow the result of an encounter with a whale. So over the years, as the picture rested in a display case in the couple’s Baltimore home, they thought of the man in the daguerreotype as the battered whaler. In December 2007, Beverly posted a scan of the image on Flickr, the photo-sharing Web site, and titled it “One-Eyed Man with Harpoon.” Soon, a whaling enthusiast e-mailed her a dissent: that is no harpoon, which suggested that the man was no whaler. Beverly, who had never heard of Gage, went online and found an astonishing tale. Steve Twomey is based in New Jersey. THE BRAIN FROM TOP TO BOTTOM. The model of the triune brain proposed by MacLean in 1970 is a useful piece of shorthand for the complex evolutionary history of the human brain.
But the brain's combination of reptilian, paleomammalian and neomammalian structures is far more intricate than a mere set of nested Russian dolls. Ever since the first mammals appeared more than 200 million years ago, the cerebral cortex has assumed greater and greater importance compared with the brain's other, older structures. Because these structures had proven their effectiveness for meeting certain fundamental needs, there was no reason for them to disappear.
Instead, evolution favoured a process of building expansions and additions, rather than rebuilding everything from the bottom up. The brains of various species of mammals (Left: all on the same scale; Right: enlarged, on various scales) This expansion of the surface of the neocortex (also known as the isocortex) is more apparent in predatory mammals than in herbivorous ones. 1616.full.pdf. Mechanisms and Functions of Theta Rhythms - Annu.-Rev.-Neurosci.-2013-Colgin.pdf. Monkeys Control a Mechanical Arm With Their Thoughts. Two monkeys with tiny sensors in their brains have learned to control a mechanical arm with just their thoughts, using it to reach for and grab food and even to adjust for the size and stickiness of morsels when necessary, scientists reported on Wednesday. The report, released online by the journal Nature, is the most striking demonstration to date of brain-machine interface technology. Scientists expect that technology will eventually allow people with spinal cord injuries and other paralyzing conditions to gain more control over their lives.
The findings suggest that brain-controlled prosthetics, while not practical, are at least technically within reach. In previous studies, researchers showed that humans who had been paralyzed for years could learn to control a cursor on a computer screen with their brain waves and that nonhuman primates could use their thoughts to move a mechanical arm, a robotic hand or a robot on a treadmill. The new experiment goes a step further.

Chapter 14: Enteric Nervous System. Enteric Nervous System One major difference between the enteric nervous system and the sympathetic and parasympathetic branches of the ANS is its extraordinary degree of local autonomy. Digestion and peristalsis occur after spinal cord transection or during spinal anesthesia, although sphincter function may be impaired (see later). NE present within the gut is the transmitter of postganglionic sympathetic neurons to the gut.
For example, if the contents of the upper intestine become overly acidic or hypertonic, an adrenergically mediated enterogastric reflex occurs, reducing the rate of gastric emptying. The adrenergic neurons, which run to the myenteric ganglia of the gastrointestinal tract from the thoracic and lumbar spinal segments, are usually inactive in the resting individual. Reflex pathways both within and external to the alimentary tract cause discharge of these neurons. Certain plexus play important roles in the enteric nervous system. Brain–computer interfaces for communication and control.
Many different disorders can disrupt the neuromuscular channels through which the brain communicates with and controls its external environment. Amyotrophic lateral sclerosis (ALS), brainstem stroke, brain or spinal cord injury, cerebral palsy, muscular dystrophies, multiple sclerosis, and numerous other diseases impair the neural pathways that control muscles or impair the muscles themselves. They affect nearly two million people in the United States alone, and far more around the world (Ficke, 1991, NABMRR, 1992, Murray and Lopez, 1996, Carter, 1997). Those most severely affected may lose all voluntary muscle control, including eye movements and respiration, and may be completely locked in to their bodies, unable to communicate in any way.
Modern life-support technology can allow most individuals, even those who are locked-in, to live long lives, so that the personal, social, and economic burdens of their disabilities are prolonged and severe. Non-Invasive Brain-to-Brain Interface (BBI): Establishing Functional Links between Two Brains. Abstract Transcranial focused ultrasound (FUS) is capable of modulating the neural activity of specific brain regions, with a potential role as a non-invasive computer-to-brain interface (CBI). In conjunction with the use of brain-to-computer interface (BCI) techniques that translate brain function to generate computer commands, we investigated the feasibility of using the FUS-based CBI to non-invasively establish a functional link between the brains of different species (i.e. human and Sprague-Dawley rat), thus creating a brain-to-brain interface (BBI). The implementation was aimed to non-invasively translate the human volunteer’s intention to stimulate a rat’s brain motor area that is responsible for the tail movement.
