In Vitro Persister Assay: A Method to Evaluate the Effect of Osmolytes on Bacterial Persistence

587
In this video, we demonstrate a method to evaluate the effect of osmolytes on the formation of bacterial persisters. The bacterial cells are first exposed to osmolytes to induce osmotic stress, triggering persister formation, then treated with antibiotics to enumerate the...

Antibiotic persistence describes the ability of small subpopulations within a sensitive isogenic population to transiently tolerate high doses of bactericidal antibiotics. The present protocol combines approaches to characterize the antibiotic persistence phenotype at the molecular and cellular levels after exposing Escherichia coli to lethal doses of...

Source: Oms, T., et al. Population and Single-Cell Analysis of Antibiotic Persistence in Escherichia coli. J. Vis. Exp. (2023)This video presents a protocol for monitoring individual bacterial cells expressing a fluorescently labeled DNA-binding protein within a microfluidic system. It illustrates how antibiotics inhibit most cells, while a subpopulation of persister cells survives the treatment and regrows following antibiotic...

Summary
This summary is machine-generated.

Neurons in the medial frontal cortex maintain persistent activity states to encode the relative value of choices during foraging. This neural activity preferentially guides foraging decisions toward more rewarding options.

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Decision Making

Background:

  • Understanding how the brain represents and uses value information to guide behavior is crucial.
  • Previous research has explored value-based decision-making, but the neural mechanisms during naturalistic foraging remain less understood.

Purpose of the Study:

  • To investigate how neurons in specific brain regions encode the relative value of options during naturalistic foraging.
  • To determine if persistent neural activity states contribute to guiding choices toward more rewarding options.

Main Methods:

  • Electrophysiological recordings in rodents during a naturalistic foraging task.
  • Analysis of neural activity in the medial frontal cortex and a nearby premotor area.
  • Correlating neural activity patterns with behavioral choices and reward outcomes.

Main Results:

  • Neurons in the medial frontal cortex, but not the premotor area, exhibited long-lasting persistent activity states.
  • These persistent activity states encoded the relative value of available foraging options.
  • The strength and duration of these activity states predicted preferential choices for more likely rewarded options.

Conclusions:

  • The medial frontal cortex plays a critical role in representing the relative value of options during foraging.
  • Long-lasting persistent neural activity states in this region are a key mechanism for guiding adaptive foraging decisions.
  • These findings provide insights into the neural basis of value-based choice and naturalistic behavior.
