Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Avoidance Learning and Learned Helplessness

Avoidance Learning and Learned Helplessness

Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Background:

Motor learning is crucial for skill acquisition.
Understanding the neural basis of motor learning, especially transfer, is key.
Covert motor learning, or mental rehearsal, is hypothesized to influence overt performance.

Purpose of the Study:

To investigate the neural mechanisms of transfer from covert to overt motor learning.
To determine if and how cortical changes from covert rehearsal impact overt performance.
To elucidate the role of motor preparatory activity in this transfer.

Main Methods:

A two-context paradigm was designed for motor learning experiments.
Subjects performed cursor movements overtly (arm movements) and covertly (brain-machine interface).
Neural activity, specifically motor cortical activity and preparatory signals, was recorded and analyzed.

Main Results:

Covert motor learning was found to transfer to overt performance.
This transfer was associated with systematic, population-level changes in motor preparatory activity.
Covert and overt contexts share initial motor preparation conditions, which are modified by covert rehearsal.

Conclusions:

Covert rehearsal facilitates overt motor learning by persistently altering motor preparatory activity.
The findings support models where motor preparation involves establishing favorable initial neural conditions.
This mechanism may offer insights into other covert cognitive processes, such as mental rehearsal.
