Rhythmic variation in heart rate and respiratory pattern are coupled in a way that optimizes the level of oxygen in the blood stream of the lungs and the body as well as saves energy in pulmonary gas exchange. It has been suggested that the cardiac cycle and respiratory pattern are coupled to neural oscillations of the brain. Yet, studies on how this rhythmic coupling is related to behavior are scarce. There is some evidence that, for example, the phase of respiration affects memory retrieval and the electrophysiological oscillatory state of the limbic system. It is also known that the phase of the cardiac cycle and hippocampal electrophysiological oscillations alone affect learning. Here, we studied whether the timing of training trials to different phases of respiration affects learning trace eyeblink conditioning in healthy adult humans. Trials consisting of a neutral conditioned stimulus (200‐ms tone) and a slightly aversive unconditioned stimulus (100‐ms air puff toward the eye), presented with a 600‐ms trace interval, were timed to either inspiration or expiration. A control group was trained regardless of respiratory phase. We found that, at the end of training, the rate of conditioned responses was higher in the group trained at expiration than it was in the other two groups. That is, brain state seems to fluctuate as a function of respiratory rhythm, and this fluctuation is also behaviorally relevant, exerting its effect on, at the least, a simple form of associative learning.

Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning
Waselius, Tomi; Xu, Weiyong; Sparre, Julia Isabella; Penttonen, Markku; Nokia, Miriam S. (American Physiological Society, 2022)Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the ... -
Hippocampal theta phase-contingent memory retrieval in delay and trace eyeblink conditioning
Waselius, Tomi; Pöllänen, Eveliina; Wikgren, Jan; Penttonen, Markku; Nokia, Miriam (Elsevier BV, 2017)Hippocampal theta oscillations (3–12 Hz) play a prominent role in learning. It has been suggested that encoding and retrieval of memories are supported by different phases of the theta cycle. Our previous study on trace ... -

Hippocampal theta activity is selectively associated with contingency detection but not discrimination in rabbit discrimination-reversal eyeblink conditioning
Nokia, Miriam; Wikgren, Jan (Wiley, 2010)The relative power of the hippocampal theta-band (∼6 Hz) activity (theta ratio) is thought to reflect a distinct neural state and has been shown to affect learning rate in classical eyeblink conditioning in rabbits. We ... -
CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats
Nokia, Miriam S.; Waselius, Tomi; Penttonen, Markku (Wiley, 2023)Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought ...
