Long-term Potentiation01:35

Long-term Potentiation

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
Imprinting01:22

Imprinting

Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.
Life Histories01:29

Life Histories

Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...
Framing Effects03:26

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in different ways based on the...

Longitudinal Studies01:26

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Area of Science:

  • Cardiology
  • Electrophysiology

Background:

  • Beth Israel Hospital excelled in interventional cardiology and cardiac imaging.
  • The hospital lacked a dedicated, modern electrophysiology (EP) section prior to 1992.

Purpose of the Study:

  • To establish a premier electrophysiology service at Beth Israel Hospital.
  • To leverage Mark Josephson's expertise in building world-class EP programs.

Main Methods:

  • Recruitment of a master clinician, scientist, and educator.
  • Strategic development of a new electrophysiology section.

Main Results:

  • Anticipation of significant transformation in the hospital's cardiology department.
  • Establishment of a strong foundation for a leading EP service.

Conclusions:

  • Mark Josephson's arrival marked a pivotal moment for Beth Israel Hospital's cardiology.
  • His leadership was expected to elevate the hospital's electrophysiology capabilities.
