Chronic Mild Stress
Objective: Unable to extract - methods section text provided does not contain experimental protocol details for chronic mild stress induction. Text contains only abstract and metadata from a Nature publication.
This is a Chronic Mild Stress protocol using rodents as the model organism. The procedure involves 4 procedural steps. Extracted from a 2012 paper published in Nature.

Chronic Mild Stress Induction
Chronic mild stress was used to induce depression-like phenotypes in rodents
Note: Specific stress parameters, duration, and protocol details not provided in the text excerpt

“depression-like phenotypes induced by chronic mild stress, by integrating behavioural, pharmacological, optogenetic and electrophysiological methods in freely moving rodents”
Optogenetic Manipulation
Bidirectional control (inhibition or excitation) of specified midbrain dopamine neurons was performed
Note: Specific optogenetic parameters, wavelengths, power, and equipment details not provided
View evidence from paper
“bidirectional control (inhibition or excitation) of specified midbrain dopamine neurons immediately and bidirectionally modulates (induces or relieves) multiple independent depression symptoms”
Behavioral Assessment
Multiple depression-related behaviors were measured in freely moving rodents
Note: Specific behavioral tests and measures not detailed in provided text

Electrophysiological Recording
Neural encoding was recorded from nucleus accumbens during behavioral tasks
Note: Specific recording parameters and equipment not provided in text
