Most hippocampal CA1 pyramidal cells in rabbits increase firing during awake sharpwave ripples and some do so in response to external stimulation and theta Nokia, Miriam S.; Waselius, Tomi; Sahramäki, Joonas; Penttonen, Markku (American Physiological Society, 2020)Hippocampus forms neural representations of real-life events including multimodal information of spatial and temporal context. These representations, i.e. organized sequences of neuronal firing are repeated during following ...
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 ...

Nokia, Miriam; Penttonen, Markku; Korhonen, Tapani; Wikgren, Jan (Elsevier, 2008)In 1978, Berry and Thompson showed that the amount of theta (3–8 Hz) activity in the spontaneous hippocampal EEG predicted learning rate in subsequent eyeblink conditioning in rabbits. More recently, the absence of theta ...
