discovery magazine journal article
Discovery Magazine Journal Article

“10 Unsolved Mysteries of the Brain”

1. Questions that assess comprehension of the journal article:

-Selected Questions

(1) What are neurons?

(2) A typical neuron in the cortex of the brain receives input from how many different neurons?

(3) What is a synapse and how does it relate to memory?

(4) What happens when you stay awake for more than 24 hours?

Dr. Rick Woodward

our current memory capacity
Our Current Memory Capacity

In today’s world, are we using our brains more or less?

Why?

-Wired Journal Article

“According to recent research, we are remembering fewer and fewer basic facts these days.”

Dr. Rick Woodward

relevant research
Relevant Research
  • Neuroscientist, Ian Robertson, polled 3,000 people and found that the younger ones were less able than there elders to recall standard personal information.
  • Asking participants to recall a relative’s birth date, 87% of the respondents over age 50 could recite it, while less than 40% of those participants under the age of 30 could do so.

Dr. Rick Woodward

relevant research1
Relevant Research
  • When asked to recall their own phone number, 1/3 of the youngsters drew a blank.
  • Do you know your cell phone number?

-Younger Americans today are the first generation to grow up with everywhere gadgets and services that exist specifically to remember things so that they don’t have to.

-Do you know any of your friend’s e-mail addresses?

Dr. Rick Woodward

go everywhere gadgets
Go-Everywhere Gadgets
  • Gadgets that remember so that you don’t have to:

(1) Blackberrys

(2) Cell phones

(3) Thumb drives

(4) Gmail

(5) Outlook

(pop ups with your lunch dates and appointments)

Phone Applications: Applications do things so you don’t have to.

Newest application that seismologist are working on.

(1) Earthquake detection system can sound an alarm in the moments before a big tremor strikes. (Scientific American April 2011)

(2) You will be notified by an application on your phone so that you can find appropriate shelter ten seconds prior to an Earthquake.

P-Wave (Primary Wave) prior to S-Wave (Shear Wave)

(Another 5 years until this technology is available)

right now in california scientific america april 2011
Right Now in California!(Scientific America: April 2011

A prototype system links together 400 seismic stations in California and will soon send alerts to a small group of test users.

Alerts will be available within 5 seconds after the first p-wave hits.

Alerts would utilize network gadgets.

A count down will be sent to your phone that marks the countdown until shaking starts!

memory capacity
Memory Capacity

1. Brain: Up to 1,000 trillion synapses.

analyzing information
Analyzing Information

A. The brain analyzes 40,000 bits of information every second.

(Sousa, 1995)

98-99% is done unconsciously!

brain morphometry
Brain Morphometry
  • Brain morphometry is a subfield of both morphology and the brain sciences, concerned with the measurements of brain structures and changes during:

(1) Development

(2) Aging

(3) Learning

(4) Disease

(5) Evolution.

brain morphometry birn
Brain Morphometry (BIRN)

Morphometry focuses on:

A. Pooling and analyzing data across neuro-imaging sites for potential relationships between anatomical differences and specific memory dysfunctions:

(1) Depression

(2)Mild Alzheimer’s Disease

(3) Mild Cognitive Impairment

Dr. Rick Woodward

getting the brain s attention
Getting the Brain’s Attention:

A. Three ways to get the brain’s attention:

(1) Survival

(2) Emotions

(3) Novelty

how is new information learned
How is new information learned?

A. New information is remembered by how it is similar to existing knowledge and recalled by how it is different.

(Comparing new information with old information: Making connections.)

Dr. Rick Woodward

let s check out your memory capacity
Let’s Check OutYour Memory Capacity

A. Take out a blank sheet of paper.

(Write on the back of this handout)

B. As you look at the next slide try to memorize as many objects from this crime scene scenario as you can.

C. You have one full minute.

D. After the time has elapsed, draw as many of the objects that you can recall.

-Ready…..

Dr. Rick Woodward

crime scene investigation
Crime Scene Investigation
  • Focus on the ten items shown below:

organization of the nervous system
Organization of the Nervous System

I. Central Nervous System consists of:

1. Brain

2. Spinal Cord

II. Peripheral Nervous System consists of:

1. Somatic Nervous System

(1) Cranial Nerves: 12 pairs

(2) Spinal Nerves: 31 pairs

2. Autonomic Nervous System

(1) Sympathetic Nervous System

(2) Parasympathetic Nervous System

Dr. Rick Woodward

central nervous system
Central Nervous System

Composed of:

brain gender
Brain Gender

A. Female brain tissue is intrinsically different from male brain tissue.

-2004 Research Study

(p.14, “Why Gender Matters,” Leonard Sax, M.D. Ph.D.)

Dr. Rick Woodward

brain gender hearing
Brain Gender & Hearing

A. Girls hearing is substantially more sensitive than boys, especially in the 1,000-4,000 Hz range, which is important for speech discrimination.

(1) For a 1,500 Hz tone played in the right ear, researchers found that the average girl baby had an acoustic response 80% greater than the response of the average baby boy.

Dr. Rick Woodward

brain gender vision
Brain Gender & Vision

A. Baby Experiment: Mobile versus Faces

(102 babies studied and videotaped)

(1) Male babies were more interested in looking at mobiles (movement: dangled and twisted).

(2) Female babies were more interested in looking at a young woman’s face.

B. Conclusion: The result of this experiment suggests that girls are born pre-wired to be interested in faces while boys are pre-wired to be more interested in moving objects.

Dr. Rick Woodward

peripheral nervous system
PeripheralNervous System

A. Consists of nerves that radiate out from the brain and spinal cord to the rest of the body.

“Fight or Flight Response”

- In response to emotional stress.

- Redirects blood flow away from the digestive system and toward the heart and skeletal muscles.
