Slide 1: We can Map just about any thing! “A map can be defined as any scheme that spells out one-to-one correspondences between two different things. In a road map, any given point on the map corresponds to some location in the larger world......” 2008, Blakeslee, pg 7 Slide 26: Body Dysmorphic Disorder Slide 27: “Research shows that your brain is teeming with body maps-maps of your body’s surface, its musculature, its intentions, its potential for action, even a map that automatically tracks and emulates the actions and intentions of other people around you.” 2008 Blakeslee, pg 11 Slide 28: Body Mandala “The sum total of your numerous, flexible, morphable body maps gives rise to the solid-feeling subjective sense of “me-ness” and to your ability to comprehend and navigate the world around you. You can think of the maps as a mandala whose overall pattern creates your embodied, feeling self. Developmentally speaking, it would be impossible to become a thinking, self aware person without them.” pg 12 Slide 32: Development Slide 35: Central Nervous System Brain and Spinal Cord Peripheral Nervous System Sensory Division Motor Division Exteroceptive “5 senses” Interoceptive “proprioception” Vestibular sense Somatic Nervous System Voluntary control Striated muscles-all fibrous muscles Conscious control Autonomic Nervous System No conscious control Sympathetic Branch Parasympathetic Branch Slide 37: Exteroceptive System Sensory nerves that respond to stimuli emanating from outside the body, the external environment. Sight Hearing Taste Smell Touch Responds to large and small changes in the environment Most if not all individuals have greater faculty in one and a sensitivity to another. What are yours? Slide 38: Interoceptive System (Body Schema) Sensory nerves that respond to stimuli emanating from inside the body Two major types: Proprioception: Your inherent sense of your body’s position and motion in space. This allows you to touch your fingers together with your eyes closed. Limb location Keeps track of load and rate of slippage in each joint, used for speed and direction Kinesthetic Sense: allows you to locate all your parts in space and your internal sense gives you feed back on heart rate, respiration, internal temperature, muscular tension, and visceral discomfort Vestibular Sense: helps the body sustain a balanced posture and maintain a relationship with gravity. Slide 39: Kinesthetic Sense This is Central to implicit, procedural memory Slide 40: Internal Sense Internal environment: Heart rate Respiration Pain Temperature Butterflies and a “Gut Feeling” Basic emotions: fear, anger, shame, sadness, interest, frustration, or happiness Each of these has a set of discrete body sensations, stimulated by outer events, brain activity, internal history. The biology of emotion in the body and brain is called AFFECT. Slide 41: Vestibular Sense Indicates when your in an upright position in relationship to the earth’s gravity. Centered in the inner ear and when disturbed can cause bouts of dizziness and vertigo. Slide 43: Somatic Memory and the Senses Our 1st impressions of an experience usually come from our senses both: Interoceptive & Exteroceptive These impressions are not encoded as words, but as the somatic sensations they are: Smells, sights, sounds, touches, tastes, movement, position, behavioral sequences, visceral reactions Slide 44: Memory in Brief Slide 45: Memory is created through neural networks Slide 46: What's a Neuron? Slide 50: Sensory Motor Cortex Slide 52: Layer one Layer two Layer Three Visual stimulation Layer Four Layer4- disappears into undifferentiated-patterns of excitation- neural networks associational cortex specialized cells that recognized very specific shapes single neuron specializing) Slide 53: Memories are kept in networks that can be rewired in case of damage Slide 57: State dependent recall The persistence of memory the buttons of time Slide 58: Bessel van der Kolk “The Body Keeps the Score!” Slide 59: The Somatic NS: Muscles, Movement, and Kinesthetic Memory Impulses for contraction of visceral muscles are primarily transmitted through nerves of the ANS Impulses for contraction of skeletal muscles are carried through the SomNS Muscle tension is chronic muscle contraction Relaxation is the absence of neural impulses Slide 60: SomNS +Kinesthetic Sense=accuracy Through the SomNS behavior, movements, and physical procedures are performed. Through Interoceptive and proprioceptive nerves they are perceived Slide 61: Learning New Movement Through SomNS + Interoception + Extroception, Kinesthetic Sense + Vestibular sense A Sequence is Feeling Intention Action Slide 62: Formation of identity and memory Via the synthesis of all of these maps Slide 64: Flow States Points of Convergence & Coordination Slide 65: Neuroplacticity Slide 66: “We see with our brain, not with our eyes” pg 15 “Both skin and the retina are two dimensional sheets, covered with sensory receptors, that allow a picture to form on them. Pg16 All our sense receptors translate different kinds of energy from the external world, no matter the source, into electric patterns sent down our nerves. These electric patterns are the universal language spoken inside the brain pg18 “Bach y Rita argued that learning plateaus were temporary part of plasticity based learning cycle in which stages of learning are followed by periods of consolidation. Though there was no apparent progress in the consolidation stage, biological changes were happening internally, as new skills became more automatic and refined. Pg 24 From Bach y Rita we have learned that the mater is more complicated and that these areas of the brain are plastic processors, connected to each other and capable of processing an unexpected variety of input. Pg 25 The brain is a far more open system than we ever imagined, and nature has gone very far to help us perceive and take in the world around us. It has given us a brain that survives in a changing world by changing itself. pg 26
