LAURA KNIGHT-JADCZYK AND JOE QUINN
Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
This presentation is not an argument against pornography. It was created for anyone who has a porn addiction, or wants to understand pornography addiction.
Science teacher Gary Wilson explains the evolutionary forces behind porn's appeal, how the brain changes in response to super-normal stimulation, what makes today's porn different from static porn of the past, and what you need to know to regain your sense of direction if you're hooked on porn.
Stress affects the size and thickness of a few different regions of your brain - the one we'll focus on here is the amygdala, an almond-shaped structure located deep within your brain. During acute stressors, the amygdala helps orchestrate the brain's rapid fight or flight response (3). This response can be adaptive in some settings, but repeated, excessive, or prolonged stress responses are thought to place people at risk for stress-related diseases (4,5). The amygdala has been shown to be a key player in mental and emotional health, with abnormal amygdala function identified in depression, anxiety, posttraumatic stress disorder, phobias, and panic disorders (6 - 8). Higher levels of perceived stress in a large sample of community adults have been associated with increased size of the amygdala (9). Moreover, some recent work suggests that reductions in perceived stress are associated with reduced amygdala density (10).
Under stress, specific functional neural changes have been observed in amygdala to prefrontal cortex (a higher order "thinking" area) circuitry, with the amygdala activating stress pathways that result in impaired prefrontal functions such as attention and working memory (3). Essentially, stress is changing how different brain regions "talk" to each other. This occurs even when your brain is at rest - it is reflected in baseline patterns of brain activity, where changes in neural functional connectivity have been shown between the amygdala and frontal brain regions in people with stress-related disorders (11 - 13).
