What is Recombinant DNA Technology?

Biology 343 Instructor: Dr. Rinehart To understand recombinant DNA technology and genetic modification, we must first understand DNA, or deoxyribonucleic acid. DNA, our genetic material, is a double helix made of nitrogenous bases, held together by hydrogen bonds and a sugar-phosphate backbone. This double helix, with antiparallel strands of genetic information, was first realized through […]

Genetics: Recombinant DNA Technology

An advantage of this recombinant DNA technology is the ability to produce these life-saving treatments for worrisome genetic disorders. A diagnosis of type-1 diabetes once came with an expiration date, now individuals with type-1 diabetes can live long, healthy, lives.

Brain Structures of Emotion

One of the primary issues is that this stress response evolved for short term use and if used to much it can cause many health issues. The stress-response essentially shuts down the “long-term projects” in order to mobilize energy and increase cardiovascular activity to push that energy.

Brain Structures Differ Based on Gender, Sex & Sexual Orientation

Of the 4 cell groups of the interstitial nuclei of the anterior hypothalamus, the 3rd group ( in the preoptic-anterior hypothalamic area—or PO-AHA), is referred to as being responsible for sexual dimorphism in reference to sexual orientation. INAH-3 is generally found to be larger in the male brain than the female brain; however, this study indicates the region is smaller, in general, in homosexual males than in heterosexual males.

Internal Mechanisms Associated With Eating & Drinking

In obese individuals, reward systems were activated during hypoglycemic and euglycemic states without PFC, higher order thought process, activation. The study found that obese individuals may be more affected by food related striatal activation when their blood sugar starts to drop.

Brain Activity During Sleep.

 EEG patterns and what they represent about cortical activity during wakefulness and the stages of sleep and REM sleep. A little luck often goes a long way regarding scientific discovery. In chapter two, we learned about Otto Loewi, who discovered the role of acetylcholine because of a dream he had. He even stated that if […]

Brain & Behavior: Nerve Cells and Nerve Impulses

Unfortunately I haven’t had nearly enough time for blogging these days. I want to continue sharing my journey and my knowledge. My end goal is a career in behavioral neuroscience, here’s a bit of what I’m learning along the way! =)  Carefully describe the differences between graded potentials and action potentials. Include how both are […]

Personality

“Hippocrates’s theory was that personality traits and human behaviors are based on four temperaments associated with fluids that he called humors. Choleric temperament or yellow bile from the liver, melancholic temperament with was the black bile from kidneys, sanguine which was red blood from the heart and finally phlegmatic temperament which was white phlegm from the lungs” (Clark & Watson, 2008; Eysenck & Eysenck, 1985; Lecci & Magnavita, 2013; Noga, 2007).
