Inactivation of prefrontal cortex attenuates behavioral arousal induced by bilateral electrical stimulation of basal forebrain in sevoflurane-anesthetized rat.
Creator: Chris W. Fields & Jon G. Dean
Duration: 6:30
The video in left panel shows behavioral arousal after bilateral electrical stimulation of basal forebrain (200 Hz, 30 s ON, 30 s OFF, 60 – 100 µA) in a female Sprague Dawley rat (session 1). Note that the behavioral arousal after electrical stimulation occurred under continuous sevoflurane exposure; the rat was breathing 1.7% sevoflurane before, during, and after recovery of the righting reflex. The right panel shows the effect of bilateral electrical stimulation in the same rat (session 2;~1 week later) after inactivation of prefrontal cortex with bilateral infusion of 156 µM tetrodotoxin. The inactivation of prefrontal cortex attenuated the arousal-promoting effects of basal forebrain stimulation. The traces on top of the video show the electroencephalographic activation induced by electrical stimulation. The lightning bolt in the upper right-hand corner indicates when the electrical stimuli were being delivered.

Chemogenetic stimulation of basal forebrain cholinergic neurons via local dialysis delivery of Compound 21 in sevoflurane-anesthetized female ChAT-Cre rat produced behavioral arousal.
Creator: Jon Dean & Chris W. Fields
Duration: 2:35
Chemogenetic stimulation of basal forebrain cholinergic neurons, via local dialysis delivery of 0.5 mM Compound 21, in sevoflurane-anesthetized female ChAT-Cre rat produced behavioral arousal. Note that the rat is continuously inhaling sevoflurane before, during, and after recovery of the righting reflex. The traces on top of the video show the electroencephalographic activation induced by Compound 21.

SAP block can be performed in supine or lateral position. Using a 12-15 MHz linear ultrasound probe, scanning starts from the midclavicular line just below the clavicle. The ribs are counted with caudal and lateral probe movement until the 4th and 5th ribs are identified in the midaxillary line. The in-plane needle approach and injection is usually performed in an anteroposterior or craniocaudal direction in the midaxillary line at the level of the 4-5th ribs with LA deposition above (superficial SAP) or below (deep SAP) the serratus anterior muscle

The PIF block is performed under ultrasound guidance, with either cranio-caudal or latero-medial needle advancement. The latter has been proposed to avoid inadvertent puncture of the perforating branch of the internal thoracic artery or the anterior perforating veins joining the internal thoracic vein, with the goal to deposit LA between the pectoralis major and intercostal muscles. The craniocaudal in-plane needle approach and injection is usually performed 1 cm lateral to the sternum at the midsternal level with LA deposition between the pectoralis major and intercostal muscles.

When performing both blocks simultaneously, single puncture site can be used to preserve near-field imaging with deposition of the LA between the layers of the serratus anterior and pectoralis minor (PECS II), followed by needle withdrawal and injection between the pectoralis minor and pectoralis major (PECS I)

The ME four chamber view is analyzed using the Automated Function Imaging (AFI) software package. The LV long axis strain model is applied to the RV to allow correct labeling of septal segments. Tracking quality is automatically assessed for each segment (green: good or red: poor). Parametric display provides measurements for each of the six RV and global strain. The latter is normal at – 22.3% with regional peak variability with basal segments below normal limits. RV myocardial region of interest is redefined and the septum de-selected to obtain RV free wall strain that is measured at approximately -22%

Identify the right jugular vein and carotid artery at the level of the thyroid cartilage on the short-axis view. Then, the probe is moved caudally following the internal jugular vein in the center of the monitor. Once the probe has reached the clavicle, it is inclined following the internal jugular vein to identify where it merges with the right subclavian vein and the underlying pleura on the long-axis view. The puncture needle is inserted using the long-axis view and advanced while identifying the needle point in real-time, until it reaches the right brachiocephalic vein.
